Figure 1. Phenotypic characterization of primary culture of CAFs isolated from metastatic CRC patient (×20). (A) CAFs isolated from the CRC patient cultured in vitro and exhibit spindle shaped morphology. Light microscopy of cultured CAFs for (B) Oil Red, (C) Giemsa stain and (D) Alzarin. CAFs: cancer associated fibroblasts; CRC: colorectal cancer
