Development of lymphoid tissue is determined by interactions between stromal organiser (LTo) and hematopoietic inducer (LTi) cells. A failure for LTo to receive appropriate activating signals during embryogenesis through lymphotoxin engagement leads a complete cessation lymph node (LN) Peyer's patch development, identifying as key population organogenesis. However, little known about the equivalent cells that induce spleen development. Here, dissociating neonatal murine re-aggregation transplant into adult mouse recipients, we have identified MAdCAM-1+CD31+CD201+ organizer cell-type critical new formation. This finding provides an insight regulation post-natal organogenesis, could be exploited in development regenerative therapies.
