This research was designed to investigate the effects of Estromon including FGF271 (Female Growth Factor 271) which was developed as a phytoestrogen for post- and pre-menopausal syndrome (PMS). The oral administration of two capsules of Estromon twice a day for 3 months significantly improved PMS (Post-/Premenopausal Syndrome) about 5 times more than placebo group (OR=5.04, 95% C.1. 1.40-18.14). In the group of 24 patients having taken Estromon, the concentration of alkaline phosphatase asn the bone marker decreased by -9.3${\pm}$9.5 IU/L after 3 months with a statistic significance. Since the concentration of osteocalcin as the other bone marker also decreased in more patients in Estromon group than in placebo group, the bone density might be expected to be improved in long-term treatment. Serum human growth hormone level increased in 17 out of 24 patients. Triglycerides decreased by -8.0${\pm}$40 (mg%) after 1 month and by -4.4${\pm}$36 (mg%) after 3 months in Estomon group while triglycerides increased in both cases in placebo group (p.0.01). Therefore, PMS patients might benefit from Estromon as a phytoestrogen supplement without any serious side effects.

BACKGROUND/OBJECTIVES: The number of diabetic patients has recently shown a rapid increase, and delayed wound healing is a major clinical complication in diabetes. In this study, the wound healing effect of Hominis placenta (HP) treatment was investigated in normal and streptozotocin-induced diabetic mice. MATERIALS/METHODS: Four full thickness wounds were created using a 4 mm biopsy punch on the dorsum. HP was injected subcutaneously at the middle region of the upper and lower wounds. Wounds were digitally photographed and wound size was measured every other day until the 14th day. Wound closure rate was analyzed using CANVAS 7SE software. Wound tissues were collected on days 2, 6, and 14 after wounding for H/E, immunohistochemistry for FGF2, and Masson's trichrome staining for collagen study. RESULTS: Significantly faster wound closure rates were observed in the HP treated group than in normal and diabetes control mice on days 6 and 8. Treatment with HP resulted in reduced localization of inflammatory cells in wounded skin at day 6 in normal mice and at day 14 in diabetic mice (P < 0.01). Expression of fibroblast growth factor (FGF) 2 showed a significant increase in the HP treated group on day 14 in both normal (P < 0.01) and diabetic mice (P < 0.05). In addition, HP treated groups showed a thicker collagen layer than no treatment groups, which was remarkable on the last day, day 14, in both normal and diabetic mice. CONCLUSIONS: Taken together, HP treatment has a beneficial effect on acceleration of cutaneous wound healing via regulation of the entire wound healing process, including inflammation, proliferation, and remodeling.

Craniosynostosis, known as a premature fusion of cranial sutures, is a developmental disorder characterized by precocious differentiation and mineralization of osteoblasts in the calvarial sutures. Recent genetic studies have demonstrated that mutation in the homeobox gene Msx2 causes Boston-type human craniosynostosis. Additionally, the phenotype of Dlx5 homozygote mutant mouse presents craniofacial abnormalities including a delayed ossification of calvarial bone. Furthermore transcription of osteocalcin, a mature osteoblast marker, is reciprocally regulated by the homeodomain proteins Msx2 and Dlx5. These facts suggest important roles of osteocalcin, Msx2 and Dlx5 genes in the calvarial bone growth and suture morphogenesis. To elucidate the function of these molecules in the early morphogenesis of mouse cranial sutures, we have first analyzed by in situ hybridization the expression of osteocalcin, Msx2 and Dlx5 genes in the developing parietal bone and sagittal suture of mouse calvaria during the embryonic (E15-E18) stage. Osteocalcin mRNA was found in the periosteum of parietal bones from E15, and gradually more highly expressed with aging. Msx2 mRNA was intensely expressed in the sutural mesenchyme, osteogenic fronts and mildly expressed in the dura mater during the embryonic stage. Dlx5 mRNA was intensely expressed osteogenic fronts and the periostem of parietal bones. To further examine the upstream signaling molecules of transcription factor Msx2 and Dlx5, we have done in vitro experiments in E15.5 mouse calvarial explants. Interestingly, implantation of BMP2-, BMP4-soaked beads onto the osteogenic fronts after 48 hours organ culture induced etopic expressions of Msx2 and Dlx5 genes. On the other hand, overexpression of $TGF{\beta}1$, GDF-6, -7, FGF-2, -4 and Shh did not induce the expression of Msx2 and Dlx5. Taken together. these data indicate that transcription factor Msx2 and Dlx5 play critical roles in the calvarial bone and suture development, and that BMP siganling is involved in the osteogenesis of calvarial bones and the maintenance of cranial sutures through regulating these two transcriotpn factors. Furthermore, different expression patterns between Msx2 and Dlx5 suggest their specific functions in the osteoblast differentiation.

Chimeric fusion proteins involving IgG have proven valuable in studying protein-protein interactions and may possess therapeutic applications as well. For example, three receptor subtypes for the natriuretic peptides, when fused to the Fc portion of human IgG ${\gamma}$ chain, were quantitatively and qualitatively indistinguishable from the native receptor, thus allowing detailed structure-function studies of the receptor. In an attempt to block human immunodeficiency virus infectivity with soluble derivatives of CD4, a CD4/IgG Fc chimeric molecule was shown to increase the plasma half life of soluble CD4 and possessed the added advantage of IgG Fc-mediated placental transfer. In the case of the KGFR, this approach provided a framework for dissection of its ligand binding domains and made it possible to demonstrate that high affinity binding sites for two ligands, aFGF and KGF, reside within different receptor Ig-like domains. Chimeric molecules fused to immunoglobulins would have the advantages of secretion from transfected cells as well as detection and purification from medium utilizing Staphylococcus aureus Protein A. In addition, where highly related receptors make their discrimination very hard due to the difficulties in generating specific immunochemical probes, IgG fusion protein with tailor-made specificities confers particular advantages to elucidate patterns of receptor distribution and expression. The approach described here may have general applications in defining ligand-receptor interactions as well as searching for specific agonists and antagonists of receptor function.

Bladder exstrophy is a rare congenital condition of the pelvis, bladder, and lower abdomen that opens the bladder against the abdominal wall, produces aberrant growth, short penis, upward curvature during erection, wide penis, and undescended testes. Exstrophy affects 1/30,000 newborns. The bladder opens against the abdominal wall in bladder exstrophy, a rare genitourinary condition. This study is vital to provide appropriate therapy choices as a basis to improve patient outcomes. This study may explain bladder exstrophy and provide treatment. Epispadias, secretory placenta, cloacal exstrophy, and other embryonic abnormalities comprise the exstrophy-spades complex. The mesenchymal layer does not migrate from the ectoderm and endoderm layers in the first trimester, affecting the cloacal membrane. Embryological problems define the exstrophy-aspidistra complex, which resembles epimedium, classic bladder, cloacal exstrophy, and other diseases. Urogenital ventral body wall anomalies expose the bladder mucosa, causing bladder exstrophy. Genetic mutations in the Hedgehog cascade pathway, Wnt signal, FGF, BMP4, Alx4, Gli3, and ISL1 cause ventral body wall closure and urinary bladder failure. External factors such as high maternal age, smoking moms, and high maternal body mass index have also been associated to bladder exstrophy. Valproic acid increases bladder exstrophy risk; chemicals and pollutants during pregnancy may increase bladder exstrophy risk. Bladder exstrophy has no identified cause despite these risk factors. Exstrophy reconstruction seals the bladder, improves bowel function, reconstructs the vaginal region, and restores urination.

The beneficial effects of adipose-derived stem cell conditioned media (ADSC-CM) for skin regeneration have previously been reported, despite the precise mechanism of how ADSC-CM promotes skin regeneration remaining unclear. ADSC-CM contains various secretomes and this may be a factor in it being a good resource for the treatment of skin conditions. It is also known that ADSC-CM produced in hypoxia conditions, in other words Advanced Adipose-Derived Stem cell Protein Extract (AAPE), has excellent skin regenerative properties. In this study, a human primary skin cell was devised to examine how AAPE affects human dermal fibroblast (HDF) and human keratinocyte (HK), which both play fundamental roles in skin regeneration. The promotion of collagen formation by HDFs was observed at 0.32 mg/ml of AAPE. AAPE treatment significantly stimulated stress fiber formation. DNA gene chips demonstrated that AAPE in HKs (p<0.05) affected the expression of 133 identifiable transcripts, which were associated with cell proliferation, migration, cell adhesion, and response to wounding. Twenty five identified proteins, including MMP, growth factor and cytokines such as CD54, FGF-2, GM-CSF, IL-4, IL-6, VEGF, TGF-${\beta}2$, TGF-${\beta}3$, MMP-1, MMP-10, and MMP-19, were contained in AAPE via antibody arrays. Thus, AAPE might activate the HK biological function and induce the collagen synthesis of HDF. These results demonstrate that AAPE has the potential to be used for clinic applications aimed at skin regeneration.

One of the steps in angiogenesis is the degradation of the underlying basement membrane via proteases. Endothelial cells release proteinases to degrade the extracellular matrix for their sprouting in vivo. In this study, we examined the effect of water extracts of Phellinus linteusis(Phellinus extracts) and combination of Phellinus extracts and fibroblast growth factor(FGF-2) on cultured porcine pulmonary artery endothelial cells(PPAECs). Phellinus extracts induced sprouting of PPAECs, which was inhibited by MMPs and plasmin inhibitors, and induced the secretion of matrix metalloproteinase-3(MMP-3) and plasmin. At high concentration of Phellinus extracts($200{\sim}400{\mu}g/mL$), the active MMP-2 secretion was induced. It is therefore, suggested that Phellinus extracts induces the sprouting of cultured endothelial cells by means of increased active MMP-2 and plasmin secretion. Also, combination with Phellinus extracts and FGF-2 produced an enhanced effect on sprouting and secretion of active MMP-2, and MMP-3 and plasmin from PPAECs.

Gamisoamsan is a prescription originated in Soamsan which is known as an anti-cancer remedy in the traditional Korean Medicine. To enhance the synergic effects of anti-cancer activity of Soamsan, this study reconstituted the original components of Soamsan with a slight modification and produced a novel herbal remedy, namely Gamisoamsan. To investigate the effects of Gamisoamsan on anti-cancer reaction, I studied the effects of Gamisoamsan on angiogenesis via chorioallantoic membrane (CAM) assay, corneal neovascularization assay and the effects on expression of growth factor which are VEGF, TGF-β, bFGF and IMUP-1. Anti-cancer effects of Gamisoamsan was also abserved through hematological parameters, tumor volume and survival rate in mice. Gamisoamsan inhibited embryonic angiogenesis of blood vessels in CAM assay and inhibited neovascularization of ral cornea. Gamisoamsan reduced cell proliferation in HT1080 cells and IC50 was 2.18 ㎎/㎖ Gamisoamsan reduced the expression of VEGF, TGF-β, bFGF and IMUP-1 which was known as vascular growth factor and this effects of Gamisoamsan was predominant than VP-16. The treatment of Gamisoamsan decreased the CT-26 cell inoculated-tumor volume in mice colon adenocarcinoma and increased mice survival which was inoculated CT-26 cells. The results of the present study suggest that Gamisoamsan extracts has a potential anti-tumor activity and may be an useful remedy to prevent and/or treat cancer.

This study investigated the hair growth effect of Schisandra chinensis extract (TS-SC) and TS-SC fermented by Lactobacillus plantarum (TS-SCLF) on human dermal papilla cells (hDPCs). The production of vascular endothelial growth factor (VEGF), insulin-like growth factor 1 (IGF-1), keratinocyte growth factor/fibroblast growth factor 7 (KGF/FGF-7) and hepatocyte growth factor (HGF), transforming growth factor beta 1 (TGF-β1) were examined. The secretion rates of VEGF and KGF/FGF-7 were high in TS-SC, and the secretion rates of IGF-1 and HGF were high in TS-SCLF. TGF-β1 was inhibited in a concentration-dependent manner in all samples. Gene expression of VEGF, IGF-1, KGF, HGF and alkaline phosphatase, relevant to hair growth, were examined. The data revealed that TS-SC and TS-SCLF successfully promoted hair growth in hDPCs. The IGF-1 gene was expressed in a dose-dependent manner in TS-SCLF. These results indicate that TS-SC and TS-SCLF fermented extract effectively promoted hair growth and gene expression relevant to hair growth in hDPCs. Used in clinical trials the test substance 'CMK-LPF01' showed a statistically significant increase in the number of hairs at 8 weeks, 16 weeks, and 24 weeks compared to before product use, and a change in hair growth, a secondary efficacy evaluation variable. Through additional research in the future, it is expected that "CMK-LPF01" can be developed as a functional material that can help alleviate symptoms of hair loss.
