Abstract

Purpose : To investigate the differentiation competence of human adipose tissue-derived stem cells (hADSCs) toward retinal lineage by inhibiting BMP and Wnt signaling.

Methods : hADSCs were divided into induction group and negative control group (NC). hADSCs of induction group were induced toward retinal lineage with a 2-step induction procedure using media containing Noggin and Dkk1, antagonist of BMP signaling and Wnt/β-catenin signaling respectively. Step 1: hADSCs were induced into neurospheres on ultra-low attachment culture plates for 3 days. Step 2: Neurospheres were transferred onto matrigel-coated culture plates and induced to differentiate for up to 24 day. hADSCs of negative control group were cultured using media only containing DF12 and 10%FBS. Cells at various time points of induction were collected and expression of markers labeling retinal progenitor cells (RPCs) , photoreceptor cells (PRCs) and retinal ganglion cells (RGCs) were revealed by RT-PCR , real-time PCR and Western-blot.

Results : The hADSCs-derived differentiated cells in the induction groups showed bright spots around nucleus, while cells in the NC group showed fibroblast-like morphology. The markers for RPCs (PAX6), PRCs (CRX, NRL and RHO), RGCs (ATOH7 and THY1), and neural precursor (NES and TUBB3) were significantly up-regulated after induction compared to negative control group.

Conclusions : hADSCs possess the potential to differentiate toward retinal lineage by inhibiting BMP and Wnt signaling.
