Ferwerda University of Oxford, UK "Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content. Kitson Almac Sciences, Northern Ireland "In principle, all scientific journals should have open access, as should be science itself. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals.
The articles are high standard and cover a wide area. In this perspective, open access journals are instrumental in fostering researches and achievements.
Open access journals offer a good alternative for free access to good quality scientific information. Many people from institutions which do not have library or cannot afford to subscribe scientific journals benefit of them on a daily basis.
The articles are among the best and cover most scientific areas.
Bendandi University Clinic of Navarre, Spain "These journals provide researchers with a platform for rapid, open access scientific communication. The articles are of high quality and broad scope.
They can be obtained from the patient known as autologous or from a donor allogeneic. Other types of stem cells include those made from embryos embryonic stem cells , isolated from tissues such as blood stem cells from the bone marrow or even a new type of stem cell made in the laboratory from a skin cell induced pluripotent stem cells.
These cells can be obtained from many different types of organs including bone marrow and fat. In the laboratory, MSCs can divide to produce large numbers of cells, and have been shown to develop into bone and cartilage.
They can also release substances that may alter how the immune system responds to injury, and encourage other types of cells to grow.
This has encouraged scientists and doctors to explore whether MSCs have a role in restoring function to damaged joints and tendons. More research is needed For most conditions, stem cell treatments are still considered experimental and have not yet been shown to be safe or effective in clinical trials.
Be wary Unfortunately, despite the lack of reliable evidence that stem cell based approaches work or are even safe, stem cell treatments are actively promoted for musculoskeletal conditions and many other health conditions by clinics in Australia and overseas. Most charge substantial fees thousands of dollars.
They also often use testimonials from celebrity patients to support their claims of success or improvement. Was ethics review and approval obtained, and if so by whom?Depending on the characteristics of the different therapeutic protocols and on the requirements of each condition, each type of stem cell has its advantages and disadvantages.
Stem Cells & Regenerative Medicine
There is much to be investigated about the specific characteristics of stem cells and about the efficacy and safety of the new drugs based on this type of cells, both embryonic as adult stem cells, for several therapeutic indications cardiovascular and ischemic diseases, diabetes, hematopoietic diseases, liver diseases. In some cases, such as preservation of umbilical cord blood, private biobanks are mainly used today, which may lead to a significant discrimination of people who cannot afford payment for such banks as compared to those who can.
Conseil de l'Europe. Any procedure related to cell therapy requires a strict control of manipulation and facilities.

Comparison of the depolarization response of human mesenchymal stem cells from different donors
They indicated that both cellular types were able to form islet-like clusters on the first day in a preconditioned culture medium. They can stay non-dividing and non-specific for years until the body summons them to repair or grow new tissue.
