We report RNA Seq analysis using Illumina nextSeq500 of human beta cells EndoC-BH1 treated with FGF2 to induce dedifferentiation. FGF2 treatment induced dedifferentiation of EndoC-BH1 cells. Indeed, we observed a strong decrease in expression of ß-cell markers, (INS, MAFB, SLC2A2, SLC30A8 and GCK). Opposingly, we identifed positive markers of human ß cell dedifferentiation, as attested by increased expression of mature ß-cell disallowed transcription factors (MYC, HES1, SOX9 and NEUROG3). Interestingly, our temporal analysis revealed that loss of expression of ß cell specific markers preceded the induction of ß cell disallowed genes. Overall design: human beta cells EndoC-BH1 were treated with FGF2 (100ng/L) during 4, 24, 72 and 144h. RNA was isolated post treatment, along with the non-treated controls, and RNA Seq was performed using Illumina nextSeq500 to generate a full transcriptome analysis of gene expression during dedifferentiation of pancreatic beta cells.

View SamplesTransplantation with low numbers of hematopoietic stem cells (HSCs), found in many of the publically accessible cryopreserved umbilical cord blood (UCB) units, leads to delayed time to engraftment, high graft failure rates, and early mortality in many patients. A chemical screen in zebrafish identified the prostaglandin compound, 16,16 dimethyl prostaglandin E2 (dmPGE2), to be a critical regulator of hematopoietic stem cell homeostasis. We hypothesized that an ex vivo modulation with dmPGE2 prior to transplantation would lead to enhanced engraftment by increasing the effective dose of hematopoietic stem cells (HSCs) in cord blood. A phase I trial of reduced-intensity double UCB transplantation was performed to evaluate safety, rates of engraftment and fractional chimerism of dmPGE2 enhanced UCB units. To explore potential causes of the lack of enhanced efficacy in the first cohort, we characterized HSCs to determine whether the prostaglandin pathway was being activated under the ex vivo incubation conditions (4C, 10M dmPGE2, 60 minutes). Incubation conditions were identified (37C, 10M dmPGE2, 120 minutes) that maximize the activation of the prostaglandin pathway by dmPGE2 in human CD34+ cells.

View SamplesUmbilical cord blood (UCB) is a valuable source of hematopoietic stem cells (HSCs) for use in allogeneic transplantation. Key advantages of UCB are rapid availability and less stringent requirements for HLA matching. However, UCB contains an inherently limited HSC count, which is associated with delayed time to engraftment, high graft failure rates and early mortality. 16,16 dimethyl prostaglandin E2 (dmPGE2) was previously identified to be a critical regulator of HSC homeostasis and we hypothesized that a brief ex vivo modulation could improve patient outcomes by increasing the effective dose of HSCs.
