Research Interests
Being overweight or obese increases the risk of the development of many diseases such
as diabetes and cardiovascular diseases. The differentiation of preadipocytes is related
to the hyperplasia of adipose tissue. One of the interests in Dr. Liu’s laboratory
is focused on the reduction of adipocyte differentiation in adipose-derived stem cells
(ASCs).
Diabetes is a serious risk factor for ischemic heart disease, which represents a significant
and growing source of morbidity and mortality despite advances in traditional treatments.
Implantation of stem/progenitor cells is an emerging strategy for therapeutic angiogenesis.
Administration of ASCs, which are easily acquired and are lack of surface histocompatibility
antigens, is beneficial for the ischemic heart and limb likely due to a paracrine
function rather than transdifferentiation. Besides secreted soluble growth factors,
cell-released microvesicles/exosomes have been recently described as new mediators
of intercellular communication. Therefore, another interest in Dr. Liu’s laboratory
is to unravel the mechanistic aspects of the proangiogenic effect of ASCs-released
microvesicles in detail. These studies will expand our currently scant knowledge of
the proangiogenic effects of stem cell-released microvesicles and set the basis for
the use of microvesicles as a novel therapeutic approach for ischemic diseases.
