Transforming growth factor-alpha (TGF-alpha) and insulin gene expression in human fetal pancreas.
Transforming growth factor-alpha (TGF-alpha) mRNA is expressed in several pancreatic cancer cell lines, but its expression during normal fetal pancreas development has not been studied. We investigated the expression of TGF-alpha, its receptor (EGF-R) and insulin mRNA and their corresponding peptides in human fetal pancreata (15-20 gestation weeks). Polymerase chain reaction (PCR) and RNAase pr...
متن کاملCytogenesis of the human fetal pancreas.
The initial survey of pancreatic islet formation in the human fetus was reported by Pearce (’03) who described the development of the islets from the primitive pancreatic tubules. The islets were first identifiable in a 54 mm fetus as clusters of small eosinophilic cells attached to the tubule but following vascularization, as observed in a 90 mm fetus, they became separated from the tubules by...
متن کاملDevelopmental mucin gene expression in the human respiratory tract.
The epithelial surface of the respiratory tract is coated with a protective film of mucus secreted by epithelial goblet and submucosal gland cells. Histology of the airway mucosa and composition of secretions during the second trimester of fetal life are known to differ from the normal adult in that these secretions show similarities with those of hypersecretory disorders. To provide informatio...
متن کاملCo-localization of neuroendocrine hormones in the human fetal pancreas.
OBJECTIVE AND DESIGN Co-localization of the four major pancreatic hormones, and also of islet amyloid polypeptide (IAPP), peptide tyrosine tyrosine (PYY), secretin and neurotensin, has been studied in the endocrine pancreas of human fetuses at 16, 18 and 22 weeks of gestation. METHODS Double and triple immunofluorescence stainings have been used. RESULTS All three fetal pancreata contained ...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
