<div><font face="Tahoma" size="+1">Dr. Ruohola-Baker's laboratory has
been focused on understanding the origin of polarity and control of
cell fate in development. In recent years it has become clear that
genes that have been implicated in human disease play an important
role in these processes. The goals of their research are to improve
understanding of the mechanisms underlying these key biological
processes and specifically to gain insight into the function of the
"disease" genes that have a significant influence on human
health. The current work is focused on the Notch- and the
Dystroglycan-pathways. In addition, they are interested in stem cell
division, self-renewal and maintenance. In particular, they have
recently shown that microRNAs regulate stem cell division and are now
analyzing the key microRNAs in the process and investigating their
cell cycle targets. These basic studies are directed towards a long
term goal of stem cell based therapeutics.</font></div>
