KGF pretreatment increases the number of IL-7–producing TECs.
Top panels, hematoxylin-eosin (H & E) staining of thymic sections from congenic BMT recipients (1400 cGy) at day 28 after BMT. Lower panels, in situ hybridization for intrathymic IL-7 transcripts from the same mice as for H & E stains. Arrows indicate IL-7+ cells.
