New York: Cells isolated from human umbilical cord tissue produce molecules that help retinal neurons from the eyes of rats grow, connect and survive, a new study reveals.

The findings implicate one family of molecules, in particular, thrombospondins that may have therapeutic potential for the treatment of degenerative eye diseases.


“By learning more about how these cells work, we are one step closer to understanding the disease states in which these cells should be studied,” said lead researcher Cagla Eroglu from Duke University Medical Centre.

Umbilical cord tissue-derived cells (hUTC) differ from umbilical cord blood cells in that they are isolated from cord tissue itself, rather than the blood.

The Duke team used an established cell culture system to determine whether and how the hUTCs might affect the growth of neurons isolated from the retinas of rat eyes.

In an experimental set-up that allowed the two types of cells to bathe in the same fluid without coming into physical contact, retinal neurons in a bath with hUTCs formed new connections between neurons called synapses, and they sprouted new ‘neurites’ tiny branches that lead to additional connections.

These cells also survived longer than rat neurons placed in a bath lacking the umbilical cord tissue-derived cells.

Blocking thrombospondins were found to reduce new connections among neurons.

“It’s exciting that thrombospondins had a really strong effect on neurite outgrowth,” said Eroglu.

The study was published in the Journal of Neuroscience.

New moms have to be careful because they have to take care of themselves and their babies.

By Dr Anil Batra

The winter comes with its own set of hassles. New moms have to be careful because they have to take care of themselves and their babies. It becomes imperative to protect babies from the harsh season.

The immune system of newborn babies is developing, which makes them susceptible to respiratory infections. But, you can take preventive measures to keep your child warm and safe. Newborn babies need extra care until their immune system becomes stronger to protect their bodies from the harmful effects of viruses and bacteria that usually become more active in the winter season. A drop in the temperature can aggravate different processes in the body, therefore, moms need to take extra care of newborn babies during winters.
