?In each group, by an inverted phase contrast microscope, cells presented with long spindle-shaped fibrocyte-like adherent growth, but no remarkable morphological changes were found.
It is a convenient method to acquire a great number of highly purified Schwann cells by enzymolysis ,and fibroblastic cells were removed by using cytosine arabinoside .
The midgut gland cell differentiation occurs at Z2, There are 4 types of cells, i. e., embryonic cell (E-cell), fibrillar cell (F-cell), blister cell (B-cell) and resorptive cell(R-cell).
