To examine the survival of neural progenitors (NPs) cells derived from human embryonic stem cells (hESCs) following subretinal (SR) transplantation in rodents. hESCs engineered to express enhanced green fluorescent protein (eGFP) were differentiated toward an NP fate using a 4-week protocol. State of differentiation was characterized by quantitative-PCR.

The Hadassah hESC Research Center's aim is to be a supplier of clinical and research-grade human embryonic stem cell (hESC) lines. In 2012, we derived the first three entirely GMP-compliant and xeno-free, fully-characterised, feeder-dependent (human umbilical cord) hESC lines developed under cleanroom conditions. In 2018, we established four new GMP and xeno-free, feeder-independent MCB hESCs under GMP conditions using commercially available reagents, media and matrix.

Teratoma tumor formation is an essential criterion in determining the pluripotency of human pluripotent stem cells. However, currently there is no consistent protocol for assessment of teratoma forming ability. Here we present detailed characterization of a teratoma assay that is based on subcutaneous co-transplantation of defined numbers of undifferentiated human embryonic stem cells (hESCs) with mitotically inactivated feeder cells and Matrigel into immunodeficient mice.

Undifferentiated human embryonic stem cells (hESCs) are currently propagated on a relatively small scale as monolayer colonies. Culture of hESCs as floating aggregates is widely used for induction of differentiation into embryoid bodies. Here we show that hESC lines can be derived from floating inner cell masses in suspension culture conditions that do not involve feeder cells or microcarriers.

Dysfunction and loss of retinal pigment epithelium (RPE) leads to degeneration of photoreceptors in age-related macular degeneration and subtypes of retinitis pigmentosa. Human embryonic stem cells (hESCs) may serve as an unlimited source of RPE cells for transplantation in these blinding conditions. Here we show the directed differentiation of hESCs toward an RPE fate under defined culture conditions.
