| Research Abstract |
In the secondary lymphoid organs in which immune responses are efficiently induced, the network of mesenchymal stromal cells support tissue architecture and immune cells behaviors. However, the detailed functions of stromal cells are still largely unclear. Technical advances to investigate lymphoid stromal cells are also required.
We established a method to efficiently isolate stromal cell fraction from mouse lymph node and for the culture of the stromal cells to make a confluent monolayer. Using this technique, we observed that isolated primary lymphocytes efficiently migrated on the stromal monolayer. Moreover, We constructed three-dimensional network of primary stromal cells using supportive meshwork substrates in vitro. We also tried to develop an animal model for genetically modifying stromal cells in vivo.
