HSCs are rare cells that have the unique ability to self-renew and differentiate into cells of all hematopoietic lineages. The lack of donors and current inability to rapidly and efficiently expand HSCs are roadblocks in the development of successful cell therapies. Thus, the challenge of ex vivo human HSC expansion remains a fertile and critically important area of investigation. Here, we show...

Murine embryonic stem (ES) cells are defined by continuous self-renewal and pluripotency. A diverse repertoire of protein isoforms arising from alternative splicing is expressed in ES cells without defined biological roles. Sall4, a transcription factor essential for pluripotency, exists as two isoforms (Sall4a and Sall4b). Both isoforms can form homodimers and a heterodimer with each other, an...
هدف: هدف از این مطالعه بررسی کمی بیان mRNA ژنSALL4 در مزنسفالن طی مراحل رشد و نمو جنینی جوجه است . مواد و روشها : در این پژوهش تجربی از تخم مرغهای نطفه دار انکوبه شده در حرارت37 تا 5/37 درجه سانتیگراد و رطوبت 60 تا 65 درصد استفاده شد. پس از شروع رشد و نمو جنینی قسمتی از بافت پروزنسفالن مغز بهطور روزانه از تخم مرغها جمع آوری گردید، از بافت تفکیک شده Total RNA استخراج و سنتز cDNA انجام ش...
Hematopoietic stem cells (HSCs) are widely used in transplantation therapy to treat a variety of blood diseases. The success of hematopoietic recovery is of high importance and closely related to the patient's morbidity and mortality after Hematopoietic stem cell transplantation (HSCT). We have previously shown that SALL4 is a potent stimulator for the expansion of human hematopoietic stem/prog...
