Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Liver Regeneration
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

Peritoneum
The peritoneum is a vital membrane that lines the abdominal cavity and covers most of the organs within it. It plays a crucial role in protecting the organs, providing a smooth surface for their movement, and facilitating various physiological processes. Understanding the anatomy and function of the peritoneum is essential for comprehending the complexities of the abdominal region.
Anatomy of the Peritoneum
The peritoneum is divided into two layers: the parietal peritoneum and the visceral...
