We aim to develop new technologies to enhance the therapeutic potency of cell-based therapies. With support from the Marcus Center for Therapeutic Cell Characterization and Manufacturing (MC3M) we are utilizing high performance liquid chromatography-mass spectrometry (HPLC-MS/MS) to characterize the anti-inflammatory potential of mesenchymal stem cell (MSCs) based on metabolism of membrane sphingolipid (SLs). We use multi-variate analysis of lipidomic network profiles and cutting imaging analysis methods to […]

Cheryl San Emeterio, Ph.D.

Cheryl San Emeterio completed her undergraduate degree in biomedical engineering at Vanderbilt University. She joined Dr. Botchwey’s lab at Georgia Tech in 2012. Cheryl’s work focuses on engineering immunomodulatory biomaterials that harness pro-regenerative myeloid cell behavior during soft tissue injury. Cheryl’s recently published work demonstrates that blood-derived non-classical monocytes are biased progenitors of wound-healing macrophages within traumatic skin […]

Thomas Turner

Thomas Turner completed his undergraduate degree in chemical engineering at the University of Florida. He joined Dr. Botchwey’s lab in 2017. Thomas’ work focuses on developing new immune autotherapies for treatment of volumetric muscle loss. In ongoing collaborative work, his is interested in applying these concepts to develop a therapeutic strategy to improve the vascularization and integration of […]

Successful tissue repair requires the activities of myeloid cells such as monocytes and macrophages that guide the progression of in ammation and healing outcome. Immunoregenerative materials leverage the function of endogenous immune cells to orchestrate complex mechanisms of repair; however, a deeper understanding of innate immune cell function in in amed tissues and their subsequent […]

Omega-3 polyunsaturated fatty acid-derived resolvins are gaining increasing recognition for their essential roles in inhibition of neutrophil invasion into inflamed tissue and promotion of macrophage phagocytosis of cellular debris as well as their egress to the lymphatics. Biomaterial-based release of lipid mediators is a largely under-explored approach more …

Hematopoietic stem and progenitor cells (HSPCs) egress from bone marrow (BM) during homeostasis and at incrased rates during stress; however, the mechanisms regulating their trafficking remain incompletely understood. Here we describe a novel role for lipid receptor, sphingosine-1-phosphate receptor 3 (S1PR3), in HSPC residence within the BM niche. HSPCs more …

Edward Botchwey, Ph.D. elected to AIMBE College of Fellows

The American Institute for Medical and Biological Engineering (AIMBE) has announced the pending induction of Dr. Edward Botchwey to its College of Fellows  for outstanding contributions to immunoregulatory biomaterials and national leadership in biomedical engineering. Each year, fellows are nominated by their peers in the medical and biological engineering community, and a select few are […]


We have devoted significant attention in recent years to the role of sphingolipid metabolism in sickle red blood cells. We have recently identified a novel mechanism of feed-forward inflammatory signaling in SCD whereby sickled RBC membrane strain increases the activity of sphingomyelinase (SMase), which contributes to membrane lipid composition and budding of cellular vesicles. This […]


An additional interest is the development of “immunologically smart” biomaterials that can tune the regenerative potential of subpopulations of leukocytes to the needs defined by the injury microenvironment. Our goal is to harness the phenotypic complexity and the division of labor among innate immune cell subsets to amplify endogenous mechanisms of tissue repair. In one […]


Our interest is to understand the microenvironmental factors that govern healing outcomes in musculoskeletal tissues and skin in order to harness endogenous mechanisms of repair. Efficient wound healing requires the angiogenic and fibrogenic activity of macrophages, which are derived at least in part from circulating monocytes that undergo differentiation post-extravasation. We focus specifically on unlocking […]
