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 کاملRetardation of wool growth in Merino sheep caused by bacteria.
A condition evidenced by retarded growth of wool with alteration of the yolk into a yellow, sticky, wax-like substance was investigated. The condition was associated with hyperaemia and cellular infiltration into the dermis in the affected areas. Three bacterial species, viz. Enterobacter aerogenes, E. agglomerans and Hafnia alvei, which could grow on the water-extractable component of wool-yol...
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.
The Chemical & Physical Structure of Merino Wool
Figure 2: Formation of a polypeptide by reaction of amino acids. (R , R and R may be the same or different 1 2 3 side groups). These contaminants are removed during processing. Clean wool, together with other animal fibres, belongs to a group of proteins known as keratins. Unlike cotton and the majority of synthetic fibres, wool does not have a homogeneous structure. Wool fibres have highly com...
