Modulating Cellular Senescence To Improve Age-Associated Wound Healing Impairment, Upasana Niyogi

Theses & Dissertations

Impaired tissue repair and regenerative ability in the aged is a major socio-economic and clinical problem. One of the likely factors associated with poor wound healing is the presence of lingering senescent cells in the wound sites. Failure to eliminate these cells has been associated with inadequate healing, excessive scarring, and abnormal skin stiffening. Thus, the objective of our study was to test interventional strategies to mitigate the negative effect of senescent cells. We hypothesized that reducing senescent cell burden and promoting non-senescent cell functionality will improve wound healing with age.

We developed a 3D in vitro senescent fibroblast populated …
