Scientists find 'better way' to grow adult stem cells


Recommended Posts

A new plastic surface which overcomes the difficulties associated with growing adult stem cells has been developed, according to scientists.

Standard surfaces have proved limited for growing large amounts and retaining the stem cells' useful characteristics.

It is hoped the discovery could lead to the creation of stem cell therapies for re-growing bone and tissue, and also for conditions such as arthritis.

The study was carried out by Glasgow and Southampton universities.

The new "nano-patterned" surface was created using a manufacturing process similar to that used to make Blu-ray discs.

The surface is covered with tiny pits, which the researchers said made it more effective in allowing stem cells to grow and spread into useful cells for therapy.

Currently, when adult stem cells are harvested from a patient, they are then cultured in a laboratory to increase the quantities of cells and create a batch of sufficient volume to kick-start the process of cellular regeneration.

At this point they can be reintroduced back into the patient.

The process of culturing is made difficult because stem cells grown on standard plastic tissue culture surfaces do not always expand to create new stem cells but instead create other cells which are of no use in therapy.

Stem cell expansion can be boosted by immersing the cells in chemical solutions, but the scientists said these methods were limited in their effectiveness.
