#4 Associating Cell Structures to Animal Healing

Adult Stem Cells

Undifferentiated cells found in mature tissues that can divide and become specific cell types within their tissue of origin. These multipotent cells serve as the body's repair system, maintaining and regenerating tissues throughout an animal's life.

Allogeneic

Cells or tissues from a genetically different individual of the same species. These transplanted materials require careful matching to prevent rejection by the recipient's immune system.

ATP (Adenosine Triphosphate)

The universal energy currency of cells, a molecule that stores and releases energy for cellular work.

Autophagy

The cellular housekeeping process where cells digest their own damaged components using lysosomes.

Autologous

Cells, tissues, or blood products taken from and used in the same individual, eliminating rejection risks.

Cell (The Cell)

The basic structural and functional unit of all living things, the smallest structure capable of performing all life processes.

Cell Membrane (Plasma Membrane)

The flexible boundary that surrounds every cell, controlling what substances enter and exit.

Cellular Respiration

The process cells use to convert glucose and oxygen into ATP energy, carbon dioxide, and water.

Cristae

The folded inner membranes of mitochondria that increase surface area for energy production.

Cytoplasm

The gel-like substance inside cells where organelles are suspended and most cellular activities occur.

Differentiation

The process by which unspecialized cells develop into specific cell types with distinct functions.

Embryonic Stem Cells

Pluripotent cells from early-stage embryos that can develop into any cell type in the body.

Endocytosis

The process by which cells take in materials from outside by engulfing them with the cell membrane.

Endoplasmic Reticulum (ER)

An extensive network of membranes within cells that synthesizes proteins and lipids and transports materials throughout the cell.

Eukaryotic Cell

Complex cells with a membrane-bound nucleus and specialized organelles, found in animals, plants, and fungi.

Exocytosis

The process by which cells release materials by packaging them in vesicles that fuse with the cell membrane.

Golgi Apparatus

The cellular 'post office' that modifies, packages, and ships proteins and lipids from the endoplasmic reticulum.

Induced Pluripotent Stem Cells (iPSCs)

Adult cells that have been reprogrammed back to an embryonic-like state, gaining the ability to become any cell type.

Lysosomes

Membrane-bound organelles containing digestive enzymes that break down cellular waste.

Mesenchymal Stem Cells (MSCs)

Adult stem cells found in bone marrow and fat tissue that can differentiate into bone, cartilage, fat, and connective tissue cells.

Mitochondria

The 'powerhouses' of cells that produce ATP energy through cellular respiration.

mRNA (Messenger RNA)

The molecular messenger that carries genetic instructions from DNA to ribosomes.

Multicellular

Organisms composed of many cells working together, with specialized cells performing different functions.

Multipotent

Stem cells that can develop into several related cell types within a specific tissue lineage.

Nucleus

The control center of eukaryotic cells that contains DNA and directs all cellular activities.

Organelle

Specialized structures within cells that perform specific functions.

Peroxisomes

Organelles that break down fatty acids for energy and detoxify harmful substances.

Plasma Membrane (Cell Membrane)

The flexible boundary surrounding every cell that controls molecular traffic in and out of the cell.

Pluripotent

Stem cells capable of developing into any cell type in the body except extraembryonic tissues.

Prokaryotic Cell

Simple cells without a membrane-bound nucleus, where genetic material floats freely in the cytoplasm.

Protein Synthesis

The cellular process of manufacturing proteins from amino acids according to genetic instructions.

Ribosomes

Small cellular structures made of RNA and protein that manufacture proteins by reading mRNA instructions.

Stem Cells

Unspecialized cells that can both self-renew and differentiate into various specialized cell types.

Tissue

A group of similar cells working together to perform a specific function.

Unicellular

Organisms consisting of a single cell that performs all necessary life functions independently.

Vacuoles

Membrane-bound storage compartments within cells that hold water, nutrients, waste products, and other materials.

Vesicles

Small membrane-bound sacs that transport materials within cells or between cells and their environment.
