简介：
Overview
This article describes the generation of lymph node/fat pad chimeras to study the origin of lymph node stromal cells. The method involves isolating lymph nodes from newborn mice and embryonic fat pads, creating chimeric lymph node-fat pads, and transplanting them under the kidney capsule of a host mouse.
