Abstract
A procedure is described for the mechanical dissociation and culturing of early stage newt regenerate blastema cells. The specified growth medium is adjusted to suitable osmolarity and consists of Leibovitz Lβ15, water, fetal calf serum, and insulin. This provides a suitable environment in which growth, proliferation, and some differentiation occur with time as evidenced by phase contrast photographs of living cultures.
