Figure 1. Expansion of BMMCs ex vivo.

Bone marrow cells from BALB/c mice were cultured for 6 weeks as described in the Methods. MCs were identified by (A) flow cytometry (c-Kit⁺FcεRIα⁺ cells) and (B, C) toluidine blue staining. BM, bone marrow; w2 – w6, weeks 2–6; original magnification of 100×. Values are presented as mean ±SEM (n = 4∼6), **P<0.05 (w5 or w6 vs. other groups). *P<0.05 (w3 or w4 vs. BM and w2). #P<0.05 (w2 vs. BM).
