Cell migration in wool follicles of sheep.
The migration of cells in wool follicles was studied by autoradiography of skin biopsies taken at half-day intervals from 2 to 5 days after intradermal injections of tritiated thymidine in 8 Corriedale sheep on different planes of nutrition. Cell migration rates were not the same in all follicles. Therefore, the shortest and longest times for cells to migrate to defined levels in the follicles ...
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.
Asymmetric distribution of alkaline phosphatase activity in the hair and wool follicles of sheep.
The strongest reaction for AP in both active and quiescent follicles was seen in the dermal papillae (Figs. 1 and 2), occasionally in the upper part only. The presence of AP in this region (Table 1), particularly during the active phase of hair growth, has now been reported in many species, suggesting that it plays an important role in hair growth. The blood vessels within the dermal papillae o...
متن کاملIdentification of microRNAs in Wool Follicles during Anagen, Catagen, and Telogen Phases in Tibetan Sheep
BACKGROUND Wool quality is one of the most important economic traits in sheep. The wool fiber is derived from specialized skin cells that are referred to as wool follicles. To understand the roles of microRNAs (miRNAs) in wool fiber growth, we detected the expression patterns of miRNAs in wool follicles at the anagen, catagen, and telogen stages from Tibetan sheep through Solexa sequencing. R...
