What Are the Common Techniques for Tissue Extraction?
Several techniques are employed for tissue extraction, each suited to different types of tissues and research needs. Some of the most common methods include:
Biopsy: This involves the removal of a small sample of tissue from a living organism. Biopsies can be performed using needles, endoscopic tools, or surgical excision. Autopsy: Post-mortem tissue extraction is performed during an autopsy to study the cause of death or disease progression. Surgical Resection: Larger tissue samples are often collected during surgeries, especially in the case of tumors or organs requiring removal. Fine Needle Aspiration (FNA): This minimally invasive technique uses a thin needle to extract cells or fluid from a lump or mass.
