Hematopoietic stem cell.

 What is hematopoietic stem cell?

Hematopoietic stem cells (HSCs) are a type of stem cell that can develop into all the different types of blood cells in the body, including red blood cells, white blood cells, and platelets. These cells are located in the bone marrow and are responsible for replenishing the body's blood cells throughout a person's lifetime. HSCs are important in treating blood-related disorders, such as leukemia and sickle cell anemia, as they can be used in bone marrow transplants to replace damaged or diseased blood cells.






Functions of hematopoietic stem cells. 

The main function of hematopoietic stem cells (HSCs) is to continuously produce all the different types of blood cells in the body throughout a person's life. HSCs have the ability to self-renew, which means they can divide and create more HSCs, as well as differentiate into progenitor cells, which can develop into different types of blood cells.


HSCs play a critical role in maintaining the body's immune system by producing white blood cells, which help fight off infections and diseases. They also produce red blood cells, which are responsible for carrying oxygen to the body's tissues and removing carbon dioxide.


In addition to their normal functions, HSCs are also used in medical treatments for certain blood-related disorders, such as leukemia, lymphoma, and sickle cell anemia. In these cases, HSCs can be extracted from a donor or from the patient's own body, then transplanted back into the patient to replace damaged or diseased blood cells.

What is the causes occur when hematopoietic stem cell are not pruducing normally? 

When hematopoietic stem cells (HSCs) are not producing normallyWhen hematopoietic stem cells (HSCs) are not producing normally, it can result in various blood-related disorders. Some of the causes of abnormal HSC production include:


1. Genetic mutations: Certain genetic mutations can affect the production and differentiation of HSCs, leading to blood disorders such as sickle cell anemia, thalassemia, and Fanconi anemia.


2. Exposure to toxins: Exposure to certain toxins, such as radiation and chemotherapy, can damage HSCs and affect their ability to produce blood cells normally.


3. Autoimmune disorders: Autoimmune disorders, such as lupus and rheumatoid arthritis, can affect the bone marrow and interfere with the production of blood cells.

What is Healing and it's chemical mediator?  Healing is a natural process of restoration and recovery, encompassing physical, emotional, and spiritual aspects. It involves the alleviation of pain, the restoration of balance and well-being, and the promotion of growth and wholeness within an individual's mind, body, and soul. Chemical Mediators of Healing?  Chemical mediators of healing can be numerous and varied. Here are five examples of important chemical mediators involved in the healing process: 1. Growth Factors: These signaling molecules stimulate cell growth, division, and tissue repair. Ex- Inflammation, collagen synthesis  2. Cytokines : These small proteins

Normal and Abnormal value of Urine? What is Urine Examination? A urine examination, also known as urinalysis, is a diagnostic test that involves analyzing a person's urine to assess their overall health and detect potential medical conditions. It provides valuable information about the chemical composition and physical properties of the urine. Here are some of the key aspects examined in a urine test: 1. Color:  The color of urine can vary and may indicate hydration levels or the presence of certain substances or medical conditions. 2. Clarity: Normal urine is typically clear. Cloudy urine may suggest an infection or other issues. 3. Specific Gravity : This measures the concentration of dissolved substances in urine, indicating hydration status. 4. pH Level: This indicates the acidity or

What is benign & malignant tumor?  Classification & nomenclature of neoplastic disease?  Chemical, physical, & biological carcinogenesis?  Clinical & gross structure of Dysplasia?  What is Invasion & Metastatis? Cytological features of malignancy?   What is Neoplasia? Neoplasia is the abnormal and uncontrolled growth of cells in the body, leading to the formation of a tumor or mass. These cells, called neoplastic cells, often lack the typical regulatory mechanisms that control cell growth. Neoplasia can be benign (non-cancerous) or malignant (cancerous), with the latter having the potential to invade nearby tissues and spread to other parts of the body. What is benign & malignant tumor? Benign Tumor A benign tumor is a non-cancerous growth of cells that does not invade nearby tissues or spread to other parts of the body. While it can grow and cause health issues if it presses against surrounding structures, it usually remains l
