Oval cells are seen in the stem cells of which of the following tissue
**Core Concept**
Oval cells, also known as hepatic progenitor cells, are a type of stem cells found in the liver that play a crucial role in liver regeneration and repair. These cells are bipotential, meaning they can differentiate into both hepatocytes and cholangiocytes.
**Why the Correct Answer is Right**
The oval cells are seen in the stem cells of the liver, specifically in the canals of Hering, which are small ducts connecting the bile canaliculi to the portal tracts. When the liver is injured, oval cells proliferate and differentiate into functional hepatocytes and cholangiocytes to replace damaged or lost cells. This process is essential for maintaining liver function and structure.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because oval cells are not typically associated with the pancreas. While the pancreas does have stem cells, they are not the same as oval cells found in the liver.
**Option B:** This option is incorrect because oval cells are not typically associated with the bone marrow. The bone marrow contains hematopoietic stem cells, which give rise to blood cells, not oval cells.
**Option C:** This option is incorrect because oval cells are not typically associated with the skin. The skin has various types of stem cells, but they are not the same as oval cells found in the liver.
**Clinical Pearl / High-Yield Fact**
Oval cells can differentiate into both hepatocytes and cholangiocytes, making them a crucial component of liver regeneration and repair. This process is essential for maintaining liver function and structure.
**Correct Answer:** C. Liver
