Abstract Cancer cell reprogramming based on aptamers with antiproliferative properties in combination with small molecules that are used for conversion iPSCs into neurons represents a new approach to reduce the probability of glioblastoma recurrence and tumor resistance to therapy. In this research we tested several combinations of factors on whole cell cultures, derived from tumor tissue after surgical resection, and on cell cultures divided in CD133 enriched and depleted populations, as CD133 marker is believed to be characteristic for glioblastoma stem cells. We showed that CD133+ and CD133- cells have a different response to tested combinations of factors and CD133-positive cells are more stable and possess stemness properties. Thus, affecting these cells will lead to decrease of therapy resistance. Moreover, we found a combination of factors that is able to inhibit proliferation of both CD133+ and CD133- cells. Our results reveal a promising strategy to improve treatment of patients with glioblastoma.

Transplantation of reprogrammed cells from accessible sources and in vivo reprogramming are potential therapies for regenerative medicine. During the last decade, genetic approaches, which mostly involved transcription factors and microRNAs, have been shown to affect cell fates. However, their potential carcinogenicity and other unexpected effects limit their translation into clinical applications. Recently, with the power of modern biology-oriented design and synthetic chemistry, as well as high-throughput screening technology, small molecules have been shown to enhance reprogramming efficiency, replace genetic factors, and help elucidate the molecular mechanisms underlying cellular plasticity and degenerative diseases. As a non-viral and non-integrating approach, small molecules not only show revolutionary capacities in generating desired exogenous cell types but also have potential as drugs that can restore tissues through repairing or reprogramming endogenous cells. Here, we focus on the recent progress made to use small molecules in cell reprogramming along with some related mechanisms to elucidate these issues.

Abstract Background: Human induced pluripotent stem cells (hiPSCs) hold great potential in disease modeling, drug screening and cell therapy. However, efficiency and costs of hiPSCs preparation still need to be improved.Methods: We screened the compounds that target signaling pathways, epigenetic modifications or metabolic-process regulation to replace the growth factors. After small molecules treatment, TRA-1-60 staining was performed to quantify the efficiency of somatic cell reprogramming. Next, small molecule cocktail induced ESCs or iPSCs were examined with pluripotent markers expression. Finally, Genome-wide gene expression profile was then analyzed by RNA-seq to illustrate the mechanism of human somatic cell reprogramming. Result: Here, we found that a dual-specificity tyrosine phosphorylation-regulated kinase inhibitor ID-8 robustly enhanced human somatic cell reprogramming by upregulation of PDK4 and activation of glycolysis. Furthermore, we identified a novel growth-factor-free hiPSC generation system using small molecules ID-8/Kartogenin (IK). Finally, we developed IK medium combined with Low-dose bFGF to support the long-term expansion of human pluripotent stem cells. IK-iPSCs showed pluripotency and normal karyotype. Conclusions: Our studies may provide a novel growth-factor-free culture system to facilitate the generation of hiPSCs for multiple application in regenerative medicine.
