Impact of B cell/lymphoid stromal cell crosstalk in B-cell physiology and malignancy.

abstract：:Previous studies have demonstrated that culture supernatants of LPS-stimulated murine splenic B lymphocytes (BLPSSN) are able to inhibit the growth of freshly isolated B cells via an IgM antibody. In this work we investigated the progress of LPS-activated B lymphocytes through the cell cycle in the presence of this an...
