An organ culture method for the maintenance of rectal biopsies over a period of 24 hours is described. Good preservation of histological architecture and continued crypt cell proliferation were shown over the culture period. The colonic enzyme alkaline phosphatase was found to rise over the period of culture. This rise was dependent upon continued protein synthesis by the cell. Changes in alkal...
BACKGROUND Wide metastasis is one of characteristics of ovarian cancer. Cancer stem cells, as a source in cancer invasion and metastasis, possess powerful potential of differentiation. Scaffolding IQ domain GTPase-activating protein 1 (IQGAP1) plays a key role in the invasion and metastasis of cancer cells, but IQGAP1's role in cancer stem cells including ovarian cancer was unclear. METHODS S...
Fibrillins 1-3 are stromal extracellular matrix proteins that play important roles in regulating TGFβ activity, which stimulates fibroblasts to proliferate and synthesize collagen. In the developing ovary, the action of stroma is initially necessary for the formation of ovigerous cords and subsequently for the formation of follicles and the surface epithelium of the ovary. FBN3 is highly expres...
BACKGROUND AND OBJECTIVE Establishing ovarian cancer cell lines will benefit researches on biological characteristics of ovarian cancer stem cells and antitumor drugs. This study was to establish a human ovarian carcinoma cell line from peritoneal effusion, and explore its biological characteristics. METHODS Cells were isolated from peritoneal effusion of an ovarian carcinoma patient, purifie...
In two epidemics of acute enterovirus conjunctivitis the diagnosis could only be established by the use of human embryonic organ cultures. In one instance cultures of ciliated respiratory epithelium proved sensitive to the virus but similar culture failed to support growth of the virus from the second outbreak which was isolated in organ cultures of conjunctiva. The virus associated with a thir...
Clinical use of CPT-11 combination chemotherapy frequently induces ovarian dysfunction in premenopausal and perimenopausal cancer patients, but its mechanism remains unclear. Mouse experiments were performed to clarify the molecular mechanism of CPT-11-induced ovarian dysfunction. Clinically therapeutic doses of CPT-11 were injected intraperitoneally into 8-week-old female MCH mice, and their o...
Background In vitro culturing and retransplantion of vitrified- warmed ovarian tissue are two ways to restore fertility after radiation or chemotherapy.This study aimed to evaluate the incidence of apoptosis in vitrified human ovarian tissue after warming, long term culturing and xenotransplantation by morphological analyses and apoptosis genes expression evaluation. MaterialsAndMethods We obta...
AIMS To test the bactericidal activity of standard organ culture medium, and to compare the sensitivity and rapidity of blood culture bottles with conventional microbiological methods for detection of bacteria and fungi inoculated in a standard cornea organ culture medium. METHODS The bactericidal activity of contaminated standard organ culture medium containing 100 IU/ml penicillin, 0.1 mg/m...
