Biology's new dimension

Article Abstract:

This article illustrates the stark differences between cells cultured in two- and three-dimensional systems. Research reveals that three-dimensional cell cultures facilitate observing gene expression and biological activities which closely mirror the events that occur in living organisms. Data indicate that mammalian cells communicate through an extracellular matrix, which contains proteins and provides mechanical properties to the tissue.

Patients warned about unproven spinal surgery

Article Abstract:

Hongyun Huang's technique is based on the theory that olfactory ensheathing cells, which normally help to link nerve cells in the nose and the brain, can help regenerate nerve cells at the site of an injury. A group of spinal experts concludes that the treatment, which involves implanting fetal cells into the spine to promote nerve-cell regeneration, has significant side effects and does not provide any benefit.
