Sebaceous gland differentiation. I. Separation, morphology and lipogenesis of isolated cells from the mouse preputial gland tumor.

Single cell suspensions have been prepared, by enzyme digestion, from the mouse preputial gland tumor and separated by flotation centrifugation into populations of different buoyant densities. These populations of cells have been shown by morphological, chemical and biochemical criteria to be in different stages of maturation. Some properties of the separated cells are described.
