Human calmodulin-like protein (CLP) is a calcium-binding protein down-regulated in a cell culture model of mammary tumorigenesis as well as in a majority of breast cancers in vivo. CLP down-regulation may be a result of the poorly differentiated state of these cell lines and tumors, or CLP expression may be incompatible with the uncontrolled cell growth associated with tumorigenesis.

Researchers have previously demonstrated that organotypic cultures of cervical tumor cell lines exhibit morphological characteristics similar to the in vivo biopsies from which they were derived (Rader et al., 1990). Both the in vivo biopsy and organotypic culture appeared undifferentiated. We have extended these studies with immunohistochemical analysis using the proliferation and differentiation...
