Measurement of cytokines.

	No DLI†	i.v.-DLI	IBM-DLI	T cells with ConA‡
IL-2 (pg/ml)	0	0	0	87·3 ± 15·5
IFN-γ (pg/ml)	0	0	0	1418·2 ± 369·4
IL-10 (pg/ml)	0	0	0	1114·6 ± 103·1
TGF-β (ng/ml)	0	0·27 ± 0·4	14·2 ± 2·4	0·6 ± 0·5

^†Bone marrow stromal cell (BMSC) culture supernatants from the recipients of intrabone marrow-bone marrow transplantation (IBM-BMT) + IBM-donor lymphocyte infusion (DLI), IBM-BMT + intravenous (i.v.)-DLI, or IBM-BMT alone (without DLI) were collected 2 weeks later. The cell supernatants were analysed for the amount of interleukin (IL)-2, IL-4, interferon (IFN)-γ and trandforming growth factor (TGF)-β by enzyme-linked immunosorbent assay.

^‡Splenic T cells from BALB/c mice were activated with concanavalin A (ConA) and used as a positive control.
