can reach out and connect with neighbors, according to a new study, completing a \u201chandshake\u201d that may show the cells are ready for trials in humans with degenerative eye disorders.<\/p>\n<p>Over a decade ago, researchers from the University of Wisconsin-Madison developed a way to grow organized clusters of cells, called organoids, that resemble the retina, the light-sensitive tissue at the back of the eye. They coaxed <a href=\"https:\/\/medicalxpress.com\/tags\/human+skin+cells\/\" rel=\"tag\" class=\"\">human skin cells<\/a> reprogrammed to act as <a href=\"https:\/\/medicalxpress.com\/tags\/stem+cells\/\" rel=\"tag\" class=\"\">stem cells<\/a> to develop into layers of several types of retinal cells that sense light and ultimately transmit what we see to the brain.<\/p>\n<p>\u201cWe wanted to use the cells from those organoids as <a href=\"https:\/\/medicalxpress.com\/tags\/replacement+parts\/\" rel=\"tag\" class=\"\">replacement parts<\/a> for the same types of cells that have been lost in the course of retinal diseases,\u201d says David Gamm, the UW-Madison ophthalmology professor and director of the McPherson Eye Research Institute whose lab developed the organoids. \u201cBut after being grown in a laboratory dish for months as compact clusters, the question remained\u2014will the cells behave appropriately after we tease them apart? Because that is key to introducing them into a patient\u2019s eye.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\ud835\udc0b\ud835\udc1a\ud835\udc1b-\ud835\udc20\ud835\udc2b\ud835\udc28\ud835\udc30\ud835\udc27
