SCaBER Cells

The SCaBER cell line is derived from a human squamous cell carcinoma of the urinary bladder. Originating from a 58-year-old male patient, this cell line retains many of the original tumor’s features, including its squamous differentiation. SCaBER cells display a distinct epithelial morphology with prominent intercellular connections such as desmosomes and interdigitated microvilli. These characteristics make it an excellent model for studying the pathology and progression of squamous cell carcinoma in the bladder.

SCaBER cells exhibit a hypotetraploid karyotype with a highly variable chromosomal number and the presence of distinctive marker chromosomes. The male karyotype includes both X and Y chromosomes, further distinguishing it from other cell lines. Ultrastructural studies reveal abundant tonofilaments, lipid bodies, and well-developed organelles such as the Golgi apparatus and rough endoplasmic reticulum. These properties have been maintained across multiple passages, ensuring consistency for long-term studies.

This cell line has been utilized in immunological research to explore tumor-specific antigens and their role in bladder cancer progression. SCaBER’s squamous differentiation is a key factor for investigations into tumor-associated antigens in squamous cell carcinomas, offering insights into potential diagnostic markers and therapeutic targets. Its well-characterized molecular and phenotypic properties make it a critical resource in urological cancer research.
