An innovative technique has been developed to convert skin cells directly into functional brain cells, representing a groundbreaking advance in regenerative medicine. This process involves carefully manipulating cellular pathways to enable the transformation, providing hope for treating neurological disorders and brain injuries. Understanding the cell cycle, particularly phases such as interphase, prophase, metaphase, anaphase, telophase, and cytokinesis, is crucial for realizing how cells can divide and differentiate into various cell types. This discovery could revolutionize treatments for neurodegenerative diseases.

Interphase • The cell starts to grow. • The call makes DNA copies. • It prepares to divide. http://emt.bu.edu/em610/em610_ol_spring_2008/yanti/interphase.html http://faculty.ccbcmd.edu/courses/bio141/lecguide/unit6/genetics/DNA/DNArep/pcinterphase.html
http://wps.aw.com/wps/media/objects/443/453744/prophase.html Prophase • Nuclear membrane and nucleus disappear • Spindle Fibers Appear http://staff.jccc.net/pdecell/celldivision/mitosis1.html
Metaphase Duplicated chromosomes move to the middle Sister chromatins meet and connect http://www.macroevolution.net/metaphase-i.html http://www.sparknotes.com/biology/cellreproduction/mitosis/section2.rhtml
http://en.wikipedia.org/wiki/Anaphase Anaphase • Sister chromatins separate and move to their own side http://morganterhune3a.edublogs.org/2011/11/14/cell-cycle-sequencing
Telophase http://www.sparknotes.com/biology/cellreproduction/mitosis/section3.rhtml • Nuclear Membrane and nucleus reappear • Chromosomes loosen up and become chromatins http://www.visualphotos.com/image/1x6011951/mitosis_telophase_immunofluorescent_lm
Cytokinesis The cell divides into two cells. http://www.vtt.fi/uutta/2008/16092008_soluttuuliajolla.jsp?lang=en http://www.sparknotes.com/biology/cellreproduction/mitosis/section3.rhtml
