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

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
