3-D hydrogel approach to study aggressive and deadly forms of brain cancer

Human glioblastoma multiforme, one of the most common, aggressive and deadly forms of brain cancer, is notoriously difficult to study. Scientists have traditionally studied cancer cells in petri dishes, which have none of the properties of the brain tissues in which these cancers grow, or in expensive animal models.

Bacillus-derived Hyaluronic acid from Novozymes Biopharma, Hyasis®, increases in vitro drug release time from under 10 minutes to approximately 15 hours

An investigation undertaken by Novozymes Biopharma DK has shown that when the corticosteroid dexamethasone is formulated in a cross-linked Hyaluronic acid (HA) hydrogel, the drug’s in vitro release time increases from under 10 minutes to approximately 15 hours. In addition, the in vivo half-life of dexamethasone is shown to plateau with stable dexamethasone concentration up to four hours after injection.

Blood vessels grown from pluripotent stem cells able to function inside mice

Researchers at Johns Hopkins have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically matched to individual patients and unlikely to be rejected by their immune systems, the investigators say.

Bioengineers find innovative ways to grow new cartilage from patient's own stem cells

Cartilage injuries are difficult to repair. Current surgical options generally involve taking a piece from another part of the injured joint and patching over the damaged area, but this approach involves damaging healthy cartilage, and a person's cartilage may still deteriorate with age.
