Using a combination of human or specially engineered mouse cells in vitro and in vivo animal models, study senior investigator Judy Lieberman, MD, PhD; study lead investigator Farokh Dotiwala, PhD, with a team lead by the Brazilian parasitologist Ricardo Gazzinelli, DSc, DVM, found that when an immune killer cell, such as a T - cell or natural killer (NK) cell, encounters a cell infected with any of three intracellular parasites (Trypanosoma cruzi, Toxoplasma gondii or Leishmania major), it releases three proteins that together kill both the parasite and the infected cell:

«With Teresa Woodruff's research using Draper's human organ system platform, we have a compelling demonstration of the importance of a microenvironment that permits cells to function in vitro as they would in vivo, and the power of being able to interconnect organ models on a platform and operate them in a stable and precise manner for weeks to months,» said Jeffrey T. Borenstein, a biomedical engineer at Draper.

Ovine bone - and marrow - derived progenitor cells and their potential for scaffold - based bone tissue engineering applications in vitro and in vivo.

The Chips are cultured under continuous flow within engineered 3D microenvironments that go beyond conventional 3D in vitro models by recapitulating in vivo intercellular interactions, spatiotemporal gradients, vascular perfusion, and mechanical forces — all key drivers of cell architecture, differentiated function, and gene expression.

The groups in vitro analyses finds that their engineered cells are more effective than non-engineered, and in vivo analyses shows some promise for the future.

ViaCyte is engineering the Encaptra ® cell delivery system to enable implanted PEC - 01 ™ cells to survive and thrive in vivo and to differentiate into functional insulin - producing cells.
