Hematopoietic stem cell/hematopoietic progenitor cell (HSC/HPC) homing to specific microenvironmental niches involves interactions between multiple receptor ligand pairs. Although CXCL12/CXCR4 plays a central role in these events, CXCR4 regulators that provide the specificity for such cells to lodge and be retained in particular niches are poorly defined.(More)
Although the use of embryonic stem cells in the assisted repair of musculoskeletal tissues holds promise, a direct comparison of this cell source with adult marrow-derived stem cells has not been undertaken. Here we have compared the osteogenic differentiation potential of human embryonic stem cells (hESC) with human adult-derived stem cells in vivo. hESC(More)
The promise of human embryo stem cells (hESCs) for regenerative medicine is offset by the ethical and practical challenges involved in sourcing eggs and embryos for this objective. In this study we sought to isolate an hESC line from clinically failed eggs, the usage of which would not conflict with donor interests to conceive. A total of 8 blastocysts were(More)
From 2006 to 2011, Roslin Cells Ltd derived 17 human embryonic stem cells (hESC) while developing (RCM1, RC-2 to -8, -10) and implementing (RC-9, -11 to -17) quality assured standards of operation in a facility operating in compliance with European Union (EU) directives and United Kingdom (UK) licensure for procurement, processing and storage of human cells(More)
Revascularisation of ischaemic tissue remains an area of substantial unmet clinical need in cardiovascular disease. Strategies to induce therapeutic angiogenesis are therefore attractive. Our recent focus has been on human embryonic stem cell (hESC) strategies since hESC can be maintained in a pluripotent state or differentiated into any desired cell type,(More)
The human embryonic stem cell line RCM-1 was derived from a failed to fertilise egg undergoing parthenogenetic stimulation. The cell line shows normal pluripotency marker expression and differentiation to three germ layers in vitro and in vivo. It has a normal 46XX female karyotype and microsatellite PCR identity, HLA and blood group typing data is(More)
The human embryonic stem cell line RCe018-A (RC-14) was derived under quality assured compliance with UK regulation, European Union Directives and International guidance for tissue procurement, processing and storage according to Good Manufacturing Practice (GMP) standards. The cell line was derived from a blastocyst stage embryo voluntarily donated as(More)
The human embryonic stem cell line RCe009-A (RC-5) was derived from a frozen and thawed Day 2 embryo voluntarily donated as unsuitable and surplus to requirement for fertility treatment following informed consent under licence from the UK Human Fertilisation and Embryology Authority. RCe009-A carries the common DF508 mutation on the cystic fibrosis(More)
The human embryonic stem cell line RCe014-A (RC-10) was derived from a fresh oocyte voluntarily donated as unsuitable and surplus to fertility requirements following ethics committee approved informed consent under licence from the UK Human Fertilisation and Embryology Authority. The cell line shows normal pluripotency marker expression and differentiation(More)
The human embryonic stem cell line RCe008-A (RC-4) was derived from a blastocyst voluntarily donated as unsuitable and surplus to fertility requirements following ethics committee approved informed consent under licence from the UK Human Fertilisation and Embryology Authority. The cell line shows normal pluripotency marker expression and differentiation to(More)
