From Cells to Bodies: A Study of Bilateral Symmetry in Flatworms - Puffin Foundation Resources
Since 1994, CELLS alive! has provided students with a learning resource for cell biology, microbiology, immunology, and microscopy through the use of mobile-friendly interactive animations, video, puzzles, quizzes and study aids. A team of scientists has mapped the regions surrounding stem cells in planarians—small flatworms that are famous for being able to regrow whole bodies from small fragments—and discovered something ...

News Medical: Study reveals how "P bodies" heavily influence a cell's fate Editing a small number of blood-forming stem cells to encode powerful antibodies turns the immune system into a living drug factory. A new study from The University of Texas at Arlington has revealed how cells control their mitochondria—the "energy producers" of cells—during the process of cell death. The discovery sheds light on ... New York Post: Human eggs created from skin cells for first time in landmark fertility study Scientists have made a landmark breakthrough that enables the creation of viable human egg cells from a skin cell, new research claims.

Human eggs created from skin cells for first time in landmark fertility study Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things. Most cells have one or more nuclei and other organelles that carry out a variety of tasks. Some single cells are complete organisms, such as a bacterium or yeast. Cell theory, developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all organisms, and that all cells come from pre-existing cells.
