Do you know STEM CELLS can cure many CHRONIC DISEASES ?

STEM CELLS

About-:
  • Undifferentiated cells 
  • Unique ability to grow into any type of cell in the body. 
  • A critical role in the development, growth, and repair of various tissues and organs in the body. 
  • Present in the developing embryo and are essential for creating and repairing all tissues and organs in the body.

Production-:
Stem cells are also found in various adult tissues, such as bone marrow, adipose tissue, and the umbilical cord.

Clasification-: 
Embryonic stem cells and Adult stem cells. 

Embryonic stem cells -:
  • These cells are derived from early stage embryos that are created during in vitro fertilization (IVF) procedures typically ones that are leftover after these procedures. 
  • These embryonic stem cells are pluripotent. This means that they can turn into more than one type of cell.
 Adult stem cells-:
  • These cells are located in various tissues in the body and can only differentiate into specific types of cells. For example, hematopoietic stem cells in bone marrow can differentiate into various blood cells, but cannot generate cells from other tissue types.
  • These cells are  found in various tissues and organs of the body such as bone marrow, skin, and brain.

Structure-:
Stem cells typically have a few main components to their structure-:

 

1. Nucleus: The nucleus is the center of the stem cell and contains its genetic material, or DNA.

2. Cytoplasm: The cytoplasm is the fluid filling the cell, which contains organelles and other cellular components.

3. Cell membrane: The cell membrane surrounds the entire cell, acting as a barrier between the cell and its surrounding environment. 
4.Stem cells also have specific surface markers on their cell membranes that allow them to be identified and sorted based on their characteristics, such as CD34 for hematopoietic stem cells.

Following is the conversion of stem cells into different types of cells -:




USES OF STEM CELLS-:

  • Stem cells have the potential to treat a wide range of diseases and conditions, including spinal cord injuries, diabetes, heart disease, Parkinson's disease,cancer, autoimmune disorders, and genetic diseases.
  •  They can be used to generate new tissues and organs for transplantation, repair damaged tissues, and develop new drugs and therapies for various diseases.
  • Research and clinical trials are being conducted to explore the effectiveness of stem cell therapies in treating these conditions.

  • It's important to note that stem cells can differentiate into a variety of cell types, which means they can also undergo structural changes as they differentiate. For example, a stem cell that differentiates into a muscle cell will have structures such as actin and myosin that are specific to muscle cells.
  • There is ongoing research in the field of stem cell therapy, with promising results being seen in clinical trials. However, the use of embryonic stem cells is a topic of ethical and political debate, as the cells are obtained from early-stage embryos. 
  • There are ongoing discussions about alternative ways of obtaining stem cells, such as through induced pluripotent stem cells (iPSCs), which are generated by reprogramming adult cells back into stem cells. 

Overall, stem cells hold great promise in the field of medicine and healthcare, and the study of these unique cells continues to expand our knowledge and understanding of the human body and its function.

ABOUT PATHOLOGY LABORATORY.....

Image
A Pathology laboratory, also known as a clinical laboratory or medical laboratory, is a facility where medical tests are performed on clinical specimens to obtain information about the health of a patient. These tests are crucial for diagnosing, monitoring, and treating various medical conditions. Pathology laboratories play a critical role in the healthcare system by providing valuable information to doctors, specialists, and other healthcare professionals.

IMPORTANCE OF RENAL/KIDNEY FUNCTION TEST(RFT)

Image
Kidneys are important organs in the body. It is important to see that their work is going on smoothly, so if any symptoms appear in the future, it would be beneficial to consult a doctor immediately. Renal function tests are used to evaluate kidney function. Kidneys play an important role in removing waste products from the body, as well as regulating electrolyte balance, blood pressure, and acid-base balance. . ABOUT KIDNEYS:- Location in the body :- ·         Kidneys are a pair of bean-shaped organs located in the abdominal cavity on either side of the spine, just under the ribcage. ·         They are retroperitoneal organs, which means they are situated behind the peritoneum (the lining of the abdominal cavity) and are not covered by it. ·         The kidneys are situated between the adrenal gland and the ureter. The top part of each kidney is located just below the diap...

मूत्रपिंडे (किडनी) ही शरीरातील महत्वाची अवयवे  आहेत.त्यांचे  कार्य  व्यवस्तिथ  चालू आहे हे पाहणे गरजेचे असते त्यामुळे पुढे काही लक्षणे दिसत असतील तर लगेच डॉक्टरांचा सल्ला घेणे फायद्याचे ठरेल. मूत्रपिंडाच्या कार्याचे मूल्यांकन करण्यासाठी रीनल फंक्शन (RFT)चाचण्या  केल्या जातात. शरीरातून टाकाऊ पदार्थ काढून टाकण्यात, तसेच इलेक्ट्रोलाइट संतुलन, रक्तदाब आणि ऍसिड-बेस बॅलन्स नियंत्रित करण्यात मूत्रपिंड महत्त्वपूर्ण भूमिका बजावतात. किडनी बद्दल  थोडक्यात   शरीरातील स्थान:-  मूत्रपिंड हे मणक्याच्या दोन्ही बाजूला उदरपोकळीत, बरगडीच्या खाली स्थित बीन-आकाराच्या अवयवांची जोडी असते. ते रेट्रोपेरिटोनियल अवयव आहेत, ज्याचा अर्थ ते पेरीटोनियमच्या मागे स्थित आहेत (उदर पोकळीचे अस्तर) आणि ते झाकलेले नाहीत. मूत्रपिंड अधिवृक्क ग्रंथी(Adrenal Gland) आणि मूत्रवाहिनी दरम्यान स्थित आहेत. प्रत्येक मूत्रपिंडाचा वरचा भाग डायफ्रामच्या अगदी खाली स्थित असतो, तर खालचा भाग श्रोणिमध्ये(Pelvis) पसरलेला असतो.     आकार:- यकृताच्या स्थितीमुळे उजवे  मूत्रपिंड डावीपेक्षा ...
