In blastocysts the region of the embryonic node was usually brilliantly fluorescent, but in some cases this zo

## Abstract Human osteosarcoma (HOS) clonal cells transformed __in vitro__ by N‐methyl‐N'‐nitro‐N‐nitroso‐guanidine (MNNG) were characterized, and compared to non‐producer HOS cells transformed by Kirsten murine sarcoma virus (Ki‐MSV). The MNNG‐ and virus‐transformed cells grew in the aggregate for
Normal dog gallbladder epithelial cells in long-term culture were used as a model to study the morphologic, genetic, and secretory processes associated with the progression to cancer formation. Dog gallbladder epithelial cells cultured on collagen-coated plates grew into polarized monolayers, could
## Abstract Using an organ culture/cell culture system, we transformed rat tracheal epithelial cells __in vitro__ by exposure to MNNG. Ten tracheal organ cultures per group were exposed twice (at days 3 and 6) to 0,0.001, 1.0 or 10.0 μg MNNG/ml of medium. Following this exposure, the explants were
