It was attended by a wide range of workers in the industry and for many it was their first ESACT meeting. The 19th ESACT meeting was to highlight the novel capabilities of the industry to move the products towards the clinic. The proceedings here include the short papers adding the knowledge of the previous meetings and provide a reference for the researcher entering, or continuing in the field of Animal Cell Technology.

Using genetic reprogramming with protein transcription factors , pluripotent stem cells with ESC-like capabilities have been derived.
Induced pluripotent stem cells differ from embryonic stem cells. They share many similar properties, such as pluripotency and differentiation potential, the expression of pluripotency genes, epigenetic patterns, embryoid body and teratoma formation, and viable chimera formation,   but there are many differences within these properties.
Despite this, inducing adult cells to be pluripotent appears to be viable. As a result of the success of these experiments, Ian Wilmut , who helped create the first cloned animal Dolly the Sheep , has announced that he will abandon somatic cell nuclear transfer as an avenue of research. Furthermore, induced pluripotent stem cells provide several therapeutic advantages.
Like ESCs, they are pluripotent. They thus have great differentiation potential; theoretically, they could produce any cell within the human body if reprogramming to pluripotency was "complete". To ensure self-renewal, stem cells undergo two types of cell division see Stem cell division and differentiation diagram. Symmetric division gives rise to two identical daughter cells both endowed with stem cell properties. Asymmetric division, on the other hand, produces only one stem cell and a progenitor cell with limited self-renewal potential.
Progenitors can go through several rounds of cell division before terminally differentiating into a mature cell. It is possible that the molecular distinction between symmetric and asymmetric divisions lies in differential segregation of cell membrane proteins such as receptors between the daughter cells. An alternative theory is that stem cells remain undifferentiated due to environmental cues in their particular niche. Stem cells differentiate when they leave that niche or no longer receive those signals. Studies in Drosophila germarium have identified the signals decapentaplegic and adherens junctions that prevent germarium stem cells from differentiating.
Stem cell therapy is the use of stem cells to treat or prevent a disease or condition. Bone marrow transplant is a form of stem cell therapy that has been used for many years without controversy. Stem cell treatments may lower symptoms of the disease or condition that is being treated. The lowering of symptoms may allow patients to reduce the drug intake of the disease or condition. Stem cell treatment may also provide knowledge for society to further stem cell understanding and future treatments.http://yapchecker.com

Stem cell treatments may require immunosuppression because of a requirement for radiation before the transplant to remove the person's previous cells, or because the patient's immune system may target the stem cells. One approach to avoid the second possibility is to use stem cells from the same patient who is being treated. Pluripotency in certain stem cells could also make it difficult to obtain a specific cell type. It is also difficult to obtain the exact cell type needed, because not all cells in a population differentiate uniformly.
Undifferentiated cells can create tissues other than desired types. Some stem cells form tumors after transplantation;  pluripotency is linked to tumor formation especially in embryonic stem cells, fetal proper stem cells, induced pluripotent stem cells. Fetal proper stem cells form tumors despite multipotency.
Some of the fundamental patents covering human embryonic stem cells are owned by the Wisconsin Alumni Research Foundation WARF — they are patents 5,,, 6,,, and 7,, invented by James A. WARF does not enforce these patents against academic scientists, but does enforce them against companies. The decision on one of the patents 7,, was appealable, while the decisions on the other two were not. Research is underway to develop various sources for stem cells, and to apply stem cell treatments for neurodegenerative diseases and conditions, diabetes , heart disease , and other conditions.
In more recent years, with the ability of scientists to isolate and culture embryonic stem cells , and with scientists' growing ability to create stem cells using somatic cell nuclear transfer and techniques to create induced pluripotent stem cells , controversy has crept in, both related to abortion politics and to human cloning. Hepatotoxicity and drug-induced liver injury account for a substantial number of failures of new drugs in development and market withdrawal, highlighting the need for screening assays such as stem cell-derived hepatocyte-like cells, that are capable of detecting toxicity early in the drug development process.
