BACKGROUND: Nowadays stem cells have been isolated successfully from the epithelial tissue of human and rodents such as skin, hair follicle, cornea, oral mucous, intestinal mucosa dental epithelial cells, and salivary glands by the Chinese or foreign researchers. But according to the vaginal mucosa stem cells (VMSCs), it is not known in the field of isolation and application.OBJECTIVE: To find out the suitable method of isolation, identification, and culture of human VMSCs.DESIGN: Observational basic study. SETTING: Department of Gynaecology and Obstetrics, the Third Affiliated Hospital of Guangzhou Medical College. MATERIALS: This study was performed in the Zhongshan Ophthalmology Center of Zhongshan Medical College from October 2004 to August 2005. Two-week gestation mice were provided by the Experimental Animal Center of Guangzhou University of Chinese Medicine. The sterile human vaginal mucosa was collected from five patients (25-38 years old) after the plastic operation of vagina from the 3rd Affiliated Hospital of Guangzhou Medical College. METHODS: Vaginal mucosa cells could be harvested from human vagina mucosa treated with trypsin-collagenase digesting. The VMSCs were selected by adhesion to type Ⅳ collagen for 20 minutes. The cell cycles of the VMSCs and primary human vaginal mucosa cells were analyzed by flow cytometry. VMSCs were cultured in vitro with 4 different media, including feeder layer cells plus epidermal total culture media, feeder layer cells plus DMEM/F12 (3:1), epidermal total culture media and DMEM/F12 (3:1). At the 12th day, their colony forming efficiency (CFE), CK19 and CK10 positive rates were compared. Then VMSCs were continuously cultured and passaged till they were apoptosis.MAIN OUTCOME MEASURES: ① Positive rate of CK19 and CK10 and G0/G1 proportion; ② Positive rate of CK19 and CK10, the colony forming efficiency (CFE) and the times be passaged when primary VMSCs were cultured in different media after 12 days. RESULTS: The cells at the G0-G1 phase cell cycle, CK19 and CK10 positive rates between the VMSCs and primary human vaginal mucosa cells were statistical different (P < 0.05). When cultured at 12th day, the VMSCs cultured with feeder layer and epidermal total culture media had the highest CFE and CK19 positive rate and lowest CK10 positive rate. They could be passaged over 15 times in vitro. CONCLUSION: It is an effective way that select VMSCs by adhesion to type Ⅳ collagen for 20 minutes. In this research, culturing VMSCs in vitro with feeder layer and epidermal total culture media was the best way to keep VMSC characteristics.

BACKGROUND:Stem cel transplantation, in recent years, has become a preferred treatment for premature ovarian failure. Umbilical cord blood mononuclear cel s containing a large number of mesenchymal stem cel s, immature stem/progenitor cel s, and endothelial progenitor cel s can be used as an important source of stem cel transplantation.
OBJECTIVE:To study the therapeutic efficacy of human umbilical cord blood mononuclear cel transplantation on radioactive premature ovarian failure in nude mice.
METHODS:120 female BALB/C nude mice were randomly divided into four groups:blank control group without any intervention;model group, intravenous transplantation group, and in situ transplantation group exposed to 60Coγrays, 0.5 Gry per day, for 30 days. After 30 days, premature ovarian failure models were made in the latter three groups. Then, nude mice in the latter three groups were given bilateral ovary injection of 10 μL DMEM, tail vein injection of 10 μL human umbilical cord blood mononuclear cel s (1×1013/L), and bilateral ovary injection of 10 μL human umbilical cord blood mononuclear cel s (1×1013/L), respectively. Thirty days after cel transplantation, serum levels of estradiol, fol icle hormone, luteinizing hormone, inhibin B and vascular endothelial growth factor were detected, cel apoptosis in the ovary tissue and cel survival were observed pathological y.
RESULTS AND CONCLUSION:After modeling, the serum levels of estradiol, inhibin B and vascular endothelial growth factor were significantly reduced (P<0.01), while fol icle hormone and luteinizing hormone levels increased (P<0.01). After transplantation, these indexes were al improved in the in situ transplantation group (P<0.01), and reduced fol icle hormone and luteinizing hormone levels were visible in the intravenous transplantation group (P<0.05, P<0.01). Compared with the model group, in situ transplantation and intravenous injection of human umbilical cord blood mononuclear cel s could effectively reduce cel apoptosis in the ovary tissue (P<0.05), and transplanted cel s were able to survive in the ovary of nude mice. Al these findings show human umbilical cord blood mononuclear cel transplantation do have curative effects on premature ovarian failure in nude mice through the inhibition of apoptosis and the regulation of hormone secretion.
