		<title>Cell Regulation And Tissue Growth</title>

		<description><![CDATA[I have often wondered how cells are regulated; divide and die at a rate that will allow tissue, organs, etc to maintain a consistent volume. It is obvious that if cells were to divide faster than they died off or could not divide fast enough to replace those that die off, that serious complications would result. Though the topic of cell senescence often revolves around telomeres or chronomeres, cell regulation is often dismissed as a "mystery". The issue with dismissing this as a "mystery" leaves me feeling a bit empty, how can we talk about cell senescence without talking about cell regulation and tissue growth. I can not see how telomere or chronomere length can regulate cell, tissue, organ, etc growth alone. If cells can divide 52 times, what keeps the cell population in check. As well, does cell regulation differ per tissue type, organ and/or person/organism? <br /><br />]]></description>
