Plasticell, a developer of innovative stem cell technologies and cell therapies, today announced it will collaborate with Anthony Nolan, a leading research organisation dedicated to saving the lives of people with blood cancers, to progress clinical development of Plasticellâ€™s ex vivo expanded cord-blood derived hematopoietic stem cell product.
Large-scale generation of patient-derived induced pluripotent stem cells to accelerate the understanding of disease biology and drug discovery. In 2012, the California Institute for Regenerative Medicine (CIRM) announced its Human iPSC Initiative, an ambitious effort to generate induced pluripotent stem cell (iPSC) lines from 3,000 donors.
The discovery by Yamanaka and Thomson in 2007 that human somatic cells can be reprogrammed to a pluripotent state (ie, induced pluripotent stem cells, iPSCs) has revolutionised cell biology.
Recently, pre-clinical and clinical studies of stem cells in regenerative medicine have demonstrated great promise as treatments for various diseases. Their ability to self-renew and differentiate makes stem cells valuable for both cell therapy and tissue engineering fields, both of which drive the demand for largescale cell expansion.
A recent market survey on stem cells in research and drug discovery showed that despite a significant amount of hype and hope around stem cells, most drug discovery-related efforts today still fall into the category of basic research and the majority of that was directed towards the oncology/cancer disease area. Human-derived stem cells were of greatest interest and the full range of stem cell types were under investigation, with no single stem cell type predominating.
With the failure rates of drug candidates continuing to present phenomenal costs to the pharmaceutical industry, this article discusses how newly emerging induced pluripotent stem cell (iPSC) technologies have the potential to be an effective tool in weeding out low quality candidates early in the process, reducing attrition costs and, ultimately, improving the percentage of new drugs to market.
Stem cells remain a hot topic in academia and industry alike, and with the potential to cause a paradigm shift where many believe in their ability to differentiate into a variety of valuable cell types. They unleashed a screening race using complex cell-based assays to evaluate cytotoxicity profiles of chemical entities, and to ultimately discover novel modulators of cell fate to be used in stem cell-based therapies. A comprehensive small molecule catalogue of modulators is emerging with no obvious value proposition as to their legitimacy towards clinical applications. Almost two decades of experimentation later, have stem cells maintained their pole position at the forefront of contemporary personalised medicine
While the jury is still out in terms of iPS cell technology and its ability to deliver a regenerative therapy or, indeed, contribute to the development of a clinical molecule, this paper argues that the progress by which this technology has been advancing is providing confidence that it will become a breakthrough technology for drug discovery.
The area of cellular therapeutics has never been readily embraced by ‘Big Pharma’, with ethical and regulatory issues even more complex and troublesome than proteins. Can stem cell therapy provide the key to unlocking a rich vein of pharmaceutical activity?
Induced pluripotent stem (iPS) cells have the potential to transform drug discovery by providing physiologically relevant cells for toxic compound identification, target validation, compound screening, and tool discovery. The technology for generating iPS cells is advancing rapidly, as is the repertoire of cell types that can be differentiated.
The remarkable potential of stem cells to generate several hundred differentiated cell types is driving their use for regenerative medicine and for supporting the traditional drug discovery and development process. However, sustained progress in these areas is dependent on advances in the ability to: grow these cells; direct, and control their differentiation; and produce the quantities needed for clinical trials and therapies in a cGMP (current Good Manufacturing Practices) environment. This article will examine advances taking place on both the lab bench and the pharmaceutical production floor that are helping to bring the promise of stem cells closer to reality.
This article explores the emerging market landscape vis--vis the use of stem cells as cellular therapeutics. For more than 40 years, hematopoietic stem cells have been utilised as cellular therapeutics in a number of malignant diseases as well as inborn genetic errors of metabolism.
Over the past decade, the use of cell-based assays has accelerated in modern drug discovery. Indeed, the majority of assays in either target validation or lead identification/optimisation all now employ cell-based technologies.
