Abstract
Bone marrow cells from CSW (Igha) mice were injected intravenously into the congeneic CWB (Ighb) mice. The lymphoid tissues of the recipient CWB mice were examined for donor type surface immunoglobulin (SΙg)-positive cells using fluorescein isothiocyanate-conjugated antiallotype serum Ighb anti-Igha. Donor type SIg-positive cells were rarely found in the recipients immediately after injection. However, the donor type B cells increased in the recipient’s spleen from days 1–2 and reached a plateau thereafter. The present method provides a useful means for studying the migration patterns and differentiation of bone marrow lymphocytes.
