Figure 5. The expressions of IGF1R, GRB2, EGFR, PTPN1, JAK2, STAT3, Caspase-1 and Bcl2 in islet grafts was analyzed by WB and cell apoptosis by TUNEL. (A) The protein expression of IGF1R, GRB2, EGFR, PTPN1, JAK2, STAT3, Caspase-1 and Bcl2 in islet grafts was detected by WB. (B) TUNEL staining for different groups.
