Although the cell-cell adhesiveness of fibroblasts is thought to be related to wound healing, the molecular basis of this adhesiveness is still unknown. We isolated five kinds of cadherin fragments from the cDNA of human fibroblasts by polymerase chain reaction (PCR). Two of the five were known cadherins: PC43, a protocadherin containing six cadherin repeats in the extracelluar domain, and human Fat, which is the human homologue of the Drosophila tumor suppressor Fat. The other three were novel cadherin fragments, and we named them cadherins FIB1, FIB2, and FIB3. The expressions of cadherins including E-, P-, and N-cadherin, PC43, human Fat, and cadherins FIB1, FIB2, and FIB3 were compared in human fibroblasts, human melanocytes, and human epidermal keratinocytes. The latter six cadherins were expressed in human fibroblasts, and cadherins FIB1 and FIB2 were fibroblast-specific. These results suggest that diverse cadherin molecules may contribute to the cell-cell adhesion in human fibroblasts.
