Toll-like receptor 4(TLR4) is a receptor that traditionally plays an important role in
immunomodulation (regulation of the immune system) and the initiation of proinflammatory
responses. TLR4 is used in the body to recognize molecular patterns of pathogens or damaged cells
from outside. However, in recent years it has also become clear that TLR4 can affect not only the
immune system, but also the function of stem cells, especially mesenchymal stem cells. Therefore,
understanding how TLR4 signaling works at the cellular and molecular level and using this knowledge
in regenerative medicine could be potentially useful, especially in the treatment of adipose-derived
mesenchymal stem cells (ADMSCs). How these cells can use TLR4 signaling when used to increase
their regenerative potential and repair tissues is an area of research. This study aims to elucidate the
multifaceted role of TLR4-mediated signaling in ADMSCs. Employing a comprehensive set of assays,
including MTT for cell viability, flow cytometry for surface marker expression, and gene expression
analysis, we demonstrate that TLR4 activation significantly modulates key aspects of ADMSC biology.
Specifically, TLR4 signaling was found to regulate ADMSCs proliferation, surface marker expression,
and regenerative capacity in a dose- and time-dependent manner. Furthermore, TLR4 activation
conferred cytoprotective effects against Doxorubicin (DOX)-induced cellular apoptosis. These
findings suggest that TLR4 signaling could be used to enhance the regenerative abilities of ADMSCs
and enable ADMSC-based therapies to be used more effectively for tissue engineering and
therapeutic purposes. However, it is important to note that research in this area needs more details
and clinical studies.
