Discovery Of Key Function Of Protein For Obtaining Blood Stem Cells As Source For Transplants
.
Researchers from IMIM (Hospital del Mar Medical Research Institute) have deciphered the function executed by a protein called β-catenin in generating blood tissue stem cells. These cells, also called haematopoietic, are used as a source for transplants that form part of the therapies to fight different types of leukaemia. The results obtained will open the doors to produce these stem cells in the laboratory and, thus, improve the quality and quantity of these surgical procedures. This will let patients with no compatible donors be able to benefit from this discovery in the future.
The study, executed jointly with the Erasmus Medical Center Stem Cell of Rotterdam and published in the Journal of Experimental Medicine, analysed a chain of molecular reactions that are produced inside some embryonic cells and that play a role in the creation of a haematopoietic stem cells. 'Our study contributes to deciphering the code that makes a precursor cell that is only found in the embryo become a haematopoietic stem cell. In order for that to happen, the β-catenin protein must be activated for a while and with a specific dosage' explains Dr Anna Bigas, head of the IMIM Stem Cells & Cancer Group and lead researcher.
This protein also plays a fundamental role in the cells that originate and maintain some types of leukaemia. 'The parallelisms between normal and leukaemia stem cells prove to us that the molecular pathways that regulate both populations are the same. For this reason, our work will help us understand the origin of these diseases', argues Dr Bigas.
In addition to embryonic stem cells, each of our body's organs has another type of stem cell that has the capacity to regenerate all the cells for the tissue in question. However, they are only formed in the embryonic stage and are maintained for the rest of our lives. Haematopoietic stem cells are part of the blood and, when they are transplanted, they are the inception for all of this tissue's cells.
At present, transplanting these cells is dependent on the availability of compatible donors. Nonetheless, there is still a high percentage of patients with no donors and that, therefore, cannot be submitted to this procedure. The results of this article lay the foundations so that, in the future, these patients can benefit from a source of laboratory-generated haematopoietic stem cells created from compatible embryonic cells or other types of expressly transformed cells.

Could your child's milk tooth save them from leukaemia ?
Is your child about to lose their milk tooth? Instead of throwing it away, you can now opt to use it to harvest stem cells in a dental stem cell bank for future use in the face of serious ailments. Now that's a tooth fairy story coming to life!.
Dental stem cell banking is fast gaining popularity as a more viable option over umbilical cord blood banking.Stem cell therapy involves a kind of intervention strategy in which healthy, new cells are introduced into a damaged tissue to treat a disease or an injury.
"The umbilical cord is a good source for blood-related cells, or hemaotopoietic cells, which can be used for blood-related diseases, like leukaemia (blood cancer). Having said that, blood-related disorders constitute only four percent of all diseases," Shailesh Gadre, founder and managing director of the company Stemade Biotech, said.

Donors answer call for Policeman with Leukaemia
When an appeal went out to find a bone marrow donor for Insp Rik Basra no one was expecting the sort of response that it generated.....and what a result !

Putting leukaemia stem cells into reverse
.
Stem cells are ‘starter’ cells that produce all the organs and tissues of the body. As a baby grows in the womb, its stem cells churn out brand new specialised cells that will form an entire body, from lungs, liver and brain to head, shoulders, knees and toes. And as adults, we still have stem cells that replenish our skin, gut and other tissues as they get worn out.
But stem cells have a rogue counterpart – cancer stem cells, which we’ve written about several times on the blog. They’re the ‘immortal’ cells that appear to lie at the heart of many cancers, including some bowel, breast and prostate cancers, and leukaemia.
Cancer stem cells appear to be more resistant to radiotherapy and chemotherapy than the cells making up the ‘bulk’ of the tumour, so understanding how these rogue stem cells originate – and how we can kill them – will be a big step forward.

Cord blood stem cell transplant hopes boosted.
A technique which may eventually remove the need for matched bone marrow transplants has been used in humans for the first time.
It is hoped that "master cells" taken from umbilical cords could be used on any patient without rejection. The latest advance, published in the journal Nature Medicine, greatly multiplies the tiny number of cells from the cord ready for a transplant. UK charity Leukaemia Research said this could be the "holy grail" for doctors.
