Latest Developments in Stem Cell Research
Stem cells harbor a significant potential in developing into different types of cells in a human body during growth and particularly early life. Furthermore, they serve as a form of internal repair system in many tissues and organs. Once a stem cell divides, it has a capability of either remaining the same or becoming another form of cell but with a specific role such as red blood cell, muscle cell, brain cell et cetera (Kimbrel, and Lanza, 2016). The history of stem cell research goes back to 1980s when Martin Evans, a professor at Cardiff University United Kingdom, identified embryonic stem cells in mice (Coghlan, 2014). This paper reviews two articles regarding the new development of stem cell research in regenerative medicine.
The article by Ratajczak et al reviews a diversity of potential sources of stem cell for regenerative therapy alongside the mechanism explaining their beneficial effects. In addition, the authors also focus on highlighting the outcome of various clinical trials involving the new developments in stem cell research for regenerative medication.
In this review, the authors observe that stem cell therapies is significantly developing and moving to the right direction. Furthermore, there is hope that the developments in stem cell research will continue to be experienced in future. It is on this basis that stem cell have been poised to become effective therapies for damaged organs which include spinal cord injury, heart injury, liver, skin damages, Parkinson disease, eye, brain, and even age. Accordingly, there is a potential for stem cell technologies to optimize the clinical discipline of regenerative discipline so as to improve the quality of life and elongate life-span. In this article, the authors observe that in future, the process of organ transplants will largely involve the suspension of stem cells which are directed to rebuild injured organs or tissues.
Nonetheless, the authors recommend that there is a need for clinical researchers and medical scientists to identify a specific group of stem cells with a capability of differentiating into different types of adult cells. In addition, the researchers need to establish effective strategies to help in reconstructing a 3 dimensional structure of an organ or tissue that is damaged. Furthermore, the authors also explain the need to come up with a strategy that can prevent the decline of a population of stem cells for longer years, and maintaining that group effectively. This will help in ensuring that this population of stem cells is not depleted prematurely and that they live to form adult tissues. Adult tissues are known to function properly thus facilitating tissue and organ regeneration.
This article by Ramachandra, and Yelledahalli evaluates the latest progresses in the field of stem cell research alongside the key ethical concerns that are associated with these developments. Accordingly, they note through a diversity of evidence that utilization of stem cells subsequently leads to successful regeneration of organs or tissues. The authors continue to observe that despite their significance in medical technologies, the ethical concerns involved in use of this development have mandated scientists to look for novel means of retrieving stem cells especially those that appear like embryonic stem cells in a way not to harm the blast cyst.
The authors perform a thorough job of revisiting the history of stem cell research, right from 1800 century up to the current time. They present key developments that have been recorded since its inception while also discussing what the future holds for this field. From this discussion, we get key insights on the origin, development, and outlook of stem cell research as an alternative to regenerative medicine.
The findings by Ramachandra, and Yelledahalli are in line with those of Robinton, and Daley (2012), as well as Ratajczak et al (2014) counterpart, who envision a bright future in stem cell research. They point out that despite the ethical challenges associated with this medical development, they are poised to become an effective treatment for regenerative conditions.
From this review, it is apparent that there has been a significant development in the field of stem cell research. Accordingly, its future as a therapy for regenerative diseases is bright, of course with impeccable medical and health result. We are also envisioning a situation where stem cells will be used to practically elongate human life, though with significant costs!
