The invention relates to material compositions comprising adult stem cells obtained from exocrine glandular tissue, and a carrier matrix in the form of a filament structure and/or of a mesh. The carrier matrix preferably consists of a plastic material which is tolerated by the body and can be ...
Which of the following is true concerning the role of Calcium in the contraction of muscle cells? A. skeletal muscle cells require a burst of calcium from the sarcoplasmic reticulum. B. smooth muscle cells require a burst of calcium from the ...
we also noticed a very small number of specific cells that expressed Piwi but not Tud in the upper middle part of the adult brain (Fig.4a). These Piwi-positive cells are usually found symmetrically located on dorsal side in both halves of the middle brain at a distance of ~...
Although ALL-1 and TRX share similarities only in the PHD fingers, and in the ZNF and SET domains, there is little doubt that they are functional homologues. The same may be true for trr and ALR, and it is likely that given the existence of SET and ZNF domains in both proteins, ...
