Following the fecundation of an egg by a sperm, the fertilized egg begins a series of cell divisions that leads to the formation of a mass of cells known as the blastula. This mass contains two types of cell masses, the trophoblast, and the inner cell mass. The trophoblast leads to the formation of the…
Adult stem cells or adult tissue-specific stem cells are non-embryonic stem cells that are found in the tissues and organs of adults. They have the specific characteristics of self-renewal and generate differentiated and specialized cells that contribute to tissue homeostasis and regeneration following injuries or diseases. They are found in several organs including the brain,…
“Cancer, a Failed By-product of Genetic Evolution?” has long been a prevailing notion in the study of oncology, suggesting that cancer is a consequence of genetic mutations gone awry during the process of evolution. This concept proposes that cancer arises as a by-product of genetic adaptations that confer advantages for survival and reproduction but inadvertently…
“Genetically Unlucky? Work On Your Epigenetics” delves into the fascinating realm where genetics and epigenetics intersect, offering insights into how individuals can transcend their genetic predispositions. In a world where “bad luck” often seems to be dictated by our genes, understanding the role of epigenetics becomes paramount. This article explores how epigenetic modifications can potentially…
Intercellular Mitochondrial Transfer, often abbreviated as IMT, is a fascinating phenomenon that has garnered significant attention in the field of cell biology and biomedical research. It refers to the process by which mitochondria, the powerhouse of cells, are transferred from one cell to another. This unique intercellular communication mechanism holds immense potential in understanding various…
The Tumor Microenvironment, a pivotal aspect in the intricate world of cancer biology, refers to the complex surroundings in which cancer cells thrive and interact. Understanding The Tumor Microenvironment is paramount for unraveling the mysteries of cancer progression and developing targeted therapeutic interventions. This dynamic ecosystem comprises a diverse array of cells, signaling molecules, and…
Why Are Some Mammals More Resistant to Cancer? It’s a question that has puzzled scientists for decades, as cancer remains one of the leading causes of death worldwide. Yet, amidst the grim statistics, certain mammalian species stand out as remarkably resistant to this devastating disease. Understanding the secrets behind their resilience not only sheds light…
How Genes Affect Human Obesity is a topic of considerable interest and importance in the field of genetics and public health. While obesity is often attributed to lifestyle factors such as diet and exercise, growing evidence suggests that genetic predisposition plays a significant role in determining an individual’s susceptibility to weight gain and obesity-related complications….
Does the Brain Produce New Cells? This question has long intrigued scientists and sparked debates in the field of neuroscience. Understanding whether the brain can generate new cells, particularly neurons, has profound implications for our understanding of brain function, development, and potential avenues for treating neurological disorders. In this article, we delve into the latest…
In the past decade, several types of viruses emerged from around the world. Some of these such as Covid-19 are already a reality that is leading to the loss of human lives and serious economic damages. Unfortunately, this epidemic is not the first nor the last one, and therefore, a better prevention system, new viral…
