Research Abstract

In this experiment, the goal is to establish a new therapy model for aplastic anemia. Our theory is that the transplanted Mesenchymal stem cell to disease model mice can reconstitute the niche cell, which can cure aplastic anemia.
At first, I analyzed Mesenchymal stem cell of Sca-1 knock out mouse.
I observed decrease of colony number as they get older.
Next, I did an experiment on Mesenchymal stem cell transplantation, but there is a problem that engraftment ratio is very low.
However, though there are individual differences, I observed the improvement of engraftment ratio with irradiation and administering of Substance P before the transplantation.
