FIG. 6.
Loss of Dpp signaling blocks plasmatocyte differentiation and upregulates Odd expression. Plasmatocyte differentiation was monitored using the specific marker, P1. (a) Plasmatocyte differentiation and Odd expression in wild-type (wt) lymph glands. (b) Odd expression and lack of plasmatocyte differentiation in dppd6 mutant lymph glands. Closed arrow mark plasmatocytes (PM), open arrow mark lack of plasmatocytes. (c) Densitometric mean of Odd expression was 6332 ± 2363 in wild-type (wt) and 8772 ± 2721in dppd6 lymph glands (P < 0.02). Lymph glands were from late-third instar larvae (144 h after egg laying). Abbreviations: dpp decapentaplegic; odd, odd-skipped. Scale bars: 100 µm.
