WebIt is shown that primary cilia are detected in a subset of cells located deep in the crypts slightly above a Paneth cell population, indicating the existence of a quiescent cell population in the human small intestine and suggesting the potential for new modes of regulation in stem cell dynamics. Primary cilia are sensory antennae located at the cell … WebWe aimed to produce an acellular human tissue scaffold with a view to test the possibility of recellularization with bone marrow stem cells to produce a tissue-engineered small intestine (TESI). Human small-bowel specimens (n = 5) were obtained from cadaveric organ donors and treated sequentially with 6% dimethyl sulfoxide in hypotonic buffer, 1% …
