We obtained eight different cell lines in the long-term bone marrow culture system that showed a germ-line configuration of the joining (J) region segments of the Ig heavy-chain (IgH) genes. Their surface markers were CD45R+, Ly-1+, Lyb-2+, cIgM-, sIgM-, Ia-, Thy-1-, Mac-1-, and IL-2R (Tac)+. Use of very young mice and the presence of IL-5 were important for preferential promotion of the surviv...

Evidence on the pre-modern relationship between wealth and fertility has so far almost entirely relied upon data from Europe.

We estimate net effects of parenthood and find that mothers receive 7.4% lower average wages compared to n...
