Good And Evil

“Jekyll and Hyde” refers to persons with an unpredictably dual personality, who are battling between good and evil within themselves In this regard, even cells consist of good and evil counterparts. Normal stem cells (NSCs) and cancer stem cells (CSCs) are two types of cells that share some similar characteristics but have distinct functions that play a major role in physiological and pathophysiological development. In reality, NSCs such as the adult and embryonic stem cells, are the good cells and the ultimate treatment used in cell therapy. CSCs are the corrupted cells that are a subpopulation of cancer cells within the cancer microenvironment that grow into a massive tumour or malignancy that needs to be treated. Hence, understanding the connection between NSCs and CSCs is important not just in cancer development but also in their therapeutic implication, which is the focus of this review.

Stem cell therapy is an approach to use cells that have the ability of self-renewal and to differentiate into different types of functional cells that are obtained from embryo and other postnatal sources to treat multiple disorders. These cells can be differentiated into different types of stem cells based on their specific characteristics to be totipotent, unipotent, multipotent or pluripotent. As potential therapy, pluripotent stem cells are considered to be the most interesting as they can be differentiated into different type of cells with similar characteristics as embryonic stem cells. Induced pluripotent stem cells (iPSCs) are adult cells that are reprogrammed genetically into stem cells from human fibroblasts through expressing genes and transcription factors at different time intervals. In this review, we will discuss the applications of stem cell therapy using iPSCs technology in treating neurodegenerative disorder such that Alzheimer’s disease (AD), Parkinson’s disease (PD), and Amyotrophic Lateral Sclerosis (ALS). We have also broadly highlighted the significance of pluripotent stem cells in stem cell therapy.

Potential Use

Stem cells are capable of regenerating tissue cells. They have an important potential use in a wide range of therapies, especially as an alternative to organ transplantation, with the advantage that they can be derived from the patient and thus avoid rejection. Embryonic stem cells are potentially capable of forming all kinds of cells. Their use is controversial however, because they are derived from early embryos and because, if they were to match the patient, they would have to be obtained using the same techniques that could, in theory, be used to produce cloned individuals. This article discusses the uses and problems of stem cell research and therapy.

With the already heightened demand placed on organ donation, stem cell therapy has become a tantalizing idea to provide glucose-responsive insulin-producing cells to Type 1 diabetic patients as an alternative to islet transplantation. Multiple groups have developed varied approaches to create a population of cells with the appropriate characteristics. Both adult and embryonic stem cells have received an enormous amount of attention as possible sources of insulin-producing cells. Although adult stem cells lack the pluripotent nature of their embryonic counterparts, they appear to avoid the ethical debate that has centred around the latter. This may limit the eventual application of embryonic stem cells, which have already shown promise in early mouse models. One must also consider the potential of stem cells to form teratomas, a complication which would prove devastating in an immunologically compromised transplant recipient. The present review looks at the progress to date in both the adult and embryonic stem cells fields as potential treatments for diabetes. We also consider some of the limitations of stem cell therapy and the potential complications that may develop with their use.

Cardiovascular disease remains the single highest global cause of death and a significant financial burden on the healthcare system. Despite the advances in medical treatments, the prevalence and mortality for heart failure remain unacceptably high. New approaches are urgently needed to reduce this burden and improve patient outcomes and quality of life. One such promising approach is stem cell therapy, including embryonic stem cells, bone marrow derived stem cells, induced pluripotent stem cells and mesenchymal stem cells. However, the cardiac microenvironment following myocardial infarction poses huge challenges with inflammation, adequate retention, engraftment and functional incorporation all crucial concerns. The lack of cardiac regeneration, cell viability and functional improvement has hindered the success of stem cell therapy in clinical settings. The use of biomaterial scaffolds in conjunction with stem cells has recently been shown to enhance the outcome of stem cell therapy for heart failure and myocardial infarction. This review outlines some of the current challenges in the treatment of heart failure and acute myocardial infarction through improving stem cell therapeutic strategies, as well as the prospect of suitable biomaterial scaffolds to enhance their efficacy and improve patient clinical outcomes.

Introduction: Each cell in human body is assigned with a specialized function to perform.  Before a cell becomes specialized, it is a stem cell. Stem cell research and therapy is progressing dramatically these days. Stem cell therapy holds enormous treatment potential for many diseases which currently have no or limited therapeutic options. Unfortunately, this potential also comes with side-effects. In this review, the positive and negative effects of regulation of stem cells will be explained.Content: Stem cells are undifferentiated cells that have potential to develop into many different cell types in the body during early life and growth. The type of stem cells are embryonic stem cells, induced pluripotent stem cells, somatic stem cells, foetal stem cells and mesenchymal stem cells. Stem cell transplantation is one form of stem cell therapy, it comes with different sources, and those are autologous and allogenic transplantation stem cells. In an autologous transplant, a patient’s own blood-forming stem cells are collected, meanwhile in an allogeneic transplant, a person’s stem cells are replaced with new stem cells obtained from a donor or from donated umbilical cord blood.Summary: Its abilities to maintain undifferentiated phenotype, self-renewing and differentiate itself into specialized cells, give rise to stem cell as a new innovation for the treatment of various diseases. In the clinical setting, stem cells are being explored in various conditions, such as in tissue repair and regeneration and autoimmune diseases therapy. But along with its benefit, stem cell therapy also holds some harm. It is known that the treatment using stem cell for curing and rehabilitation has the risk in tumor formation.

Stem Cell Treatment

The controversy surrounding stem cell research led to an intense debate about ethics. Up until the recent years, the research method mainly focused on Embryonic Stem Cells, which involves taking tissue from an aborted embryo to get proper material to study. This is typically done just days after conception or between the 5th and 9th week. Since then, researchers have moved on to more ethical study methods, such as Induced Pluripotent Stem Cells (iPS). iPS is artificially derived from a non-pluripotent cell, such as adult somatic cells. This is probably an important advancement in stem cell research, since it allows researchers to obtain pluripotent stem cells, which are important in research, without the controversial use of embryos. Nowadays stem cell treatment has been spreaded throughout the world. It has also been grown commercially in developed countries. This paper assesses the stem cell treatment as well as its impact in human life. It also examines specific stem cell therapy market that proves far reaching effect in world economy. Though various organizations have made it as a controversial issue the analysis shows that stem cell treatment has brought positive dimension in human society. A discussion has been made about the ethical issues of stem cell research and therapy; which focus how recent biotechnology and biological understandings of development narrow the debate. It is thought that one day it may be the major key to treat various diseases. DOI: http://dx.doi.org/10.3329/bioethics.v1i3.9631 Bangladesh Journal of Bioethics 2010; 1(3): 22-34
