  What Are Brain Stem Cells ? Neural stem cells (NSCs) are multipotent cells that can generate neurons, astrocytes, and oligodendrocytes. They are found in specific regions of the brain, such as the subventricular zone (SVZ) and the hippocampus. Their main functions include building the nervous system during development, repairing damaged tissue, and supporting learning and memory through neurogenesis. Key Roles Development: NSCs produce progenitor cells that form neurons and glia. Repair: They can replace damaged cells after injury or disease. Plasticity: They contribute to memory and learning by generating new neurons in the hippocampus. Medical Importance Neurodegenerative diseases: Research explores NSCs for treating Parkinson’s, Alzheimer’s, and ALS. Spinal cord injuries: Potential to regenerate motor neurons and restore function. Cancer connection: Mutations in NSCs can lead to brain tumors such as glioblastoma. Challenges and Risks Controlling differentiation is diffic...

  Understanding Blood Cancer: More Than Just a Diagnosis Intro: Blood cancer isn’t a single disease — it’s an umbrella term for conditions like leukemia, lymphoma, and myeloma. Each affects the way blood cells grow and function, often disrupting the body’s ability to fight infection or carry oxygen. Body: What it is: Blood cancers start in the bone marrow or lymphatic system. Types: Leukemia — abnormal white blood cells crowd out healthy ones. Lymphoma — cancer of the lymphatic system, which helps fight infection. Myeloma — cancer of plasma cells that produce antibodies. Signs to watch: Fatigue, frequent infections, unexplained bruising, or swollen lymph nodes. Hope in research: Advances in immunotherapy and targeted treatments are giving patients longer, healthier lives. Closing: Blood cancer is challenging, but knowledge is power. By learning the basics, we can support those affected and appreciate the breakthroughs that bring hope every day
