One most recent study first reported the feasibility of using undifferentiated hPSC molarity and dilution for cardiac differentiation in suspension by small molecules modulating Wnt pathway (Kempf et al., 2014). With a fixed differentiation condition without controlling cell aggregate size, the aut

2018-10-20

Mammalian muscle differentiation is governed by the expression of a series of master regulatory transcription factors, collectively called myogenic regulatory factors (MRFs) (Bentzinger et al., 2012; Molkentin and Olson, 1996). Proliferating myoblasts start expressing MRFs, i.e. MyoD, myogenin, MRF4

Microarray-based global hierarchical clustering clearly separated all the directly isolated keratinocyte populations. In the first round of analysis () where we focused on known and well characterized populations the Plet population clearly separated from the rest of the populations, which is probab

Several studies have reported the existence of rare CD34− HSCs upstream of the major population of CD34+ HSCs in the human hematopoietic hierarchy (Anjos-Afonso et al., 2013; Bhatia et al., 1998). Interestingly, the first HSCs found in the human embryo are CD34+ and give rise exclusively to a CD34+C

Results Discussion Here, we demonstrate that the status of the X chromosome is dynamic during human female somatic cell reprogramming. Extending previous studies that examined X chromosome status in iPSCs after completion of reprogramming, we determined the change of X chromosome status in vol

Retinal degenerative diseases such as inherited or age-related eye diseases resulting in the loss of photoreceptors are the leading cause of blindness in Europe. To date, around 4% of the western world population suffers from one of these diseases, and unfortunately, no cures exist to treat the majo

Introduction Reprogramming somatic stavudine manufacturer to induced pluripotent stem cells (iPSCs) holds great promise for disease modeling and therapeutic applications. Among the challenges that remain is the extended time frame and variable efficiency of transcription factor-based reprogramming

2018-10-20

To test whether the direction of the genomic strand targeted by the gRNA molecule was a factor in its capacity to recruit dCas9 and activate expression of the endogenous locus, we designed a gRNA molecule (gRNA4) targeting the minus strand of the same region for which gRNA3 was designed (PAM separat

A recent study indicated that XIST expression can be lost upon prolonged passaging of female hiPSCs, referred to as “erosion of XCI” (Mekhoubad et al., 2012). This epigenetic erosion was found to be irreversible and correlated with a loss of differentiation characteristics and is very relevant for d

2018-10-20

Recently, several clinical trials of stem-cell-based therapy for SCI using either human NS/PCs (Cummings et al., 2005; Salazar et al., 2010) or human ESC-derived OPCs (Strauss, 2010) have been initiated. Compared with these stem cells, iPSCs raise fewer ethical concerns in certain countries (Nori et

2018-10-20

Another question to address is the potential influence of the degree of maturity of prepubertal donor tissue on the success of transplantation. Donor age-dependent differential gene expression and subsequent protein expression have been reported in tissue grafts. This could alter the initial ability

2018-10-20

Because suicide systems can be designed not to evoke cross-resistance to conventional agents, they can potentiate therapy—efficiently inducing apoptosis in transduced cells—without increasing toxicity. However, many suicide systems have drawbacks, proving less clinically effective than desired. HSV-

Others have reported both B and T cell effects after osteolineage cell deletion (Ding and Morrison, 2013) but the promoter used in some of those studies, Col1(2.3), extends through many cell stages of osteolineage progression. Here we define that these osteolineage cell states provide distinctive fu

2018-10-20

These data suggest that niches are not limited to the governance of stem cells (Wu et al., 2009; Yu et al., 2015a), and the definition of “progenitor niches” may offer new ways to understand the regulation of tissue composition and function. We recently demonstrated that selective deletion of cells
