Can pig brain cells be implanted into the human brain or can treat neurological diseases?

If you need to implant pig cells into your brain, would you agree? Most people face this problem and should not hesitate to say "no", but for Parkinson's critically ill patients, in order to prevent the disease from worsening, they will abandon their concerns and try boldly.

According to a recent report by New Scientist, after four patients with Parkinson's disease participated in clinical trials showing attractive prospects, New Zealand's Living Cell Technologies has launched a larger clinical trial to recruit 18 patients. A surgical injection of a pig brain cell into their brain continues to validate the effects of active cell technology therapy.

Because cells of the brain endocrine dopamine are gradually reduced or lose function, patients with Parkinson's disease cannot produce enough dopamine to control their behavior, thus showing symptoms such as tremor or difficulty in movement, and the condition will gradually deteriorate over time. The existing Parkinson's disease drugs mainly perform functions instead of dopamine, but after a few years of taking, the efficacy will decrease or even disappear.

Active Cell Technology is conducting a new treatment for human clinical trials, which are capsules of choroid plexus cells extracted from pig brain and implanted in the brains of patients with Parkinson's disease. The choroid plexus is the choroid composed of the pia mater and its upper blood vessels and the ependymal epithelium, and is the main structure for producing cerebrospinal fluid. The cerebrospinal fluid secreted by the choroid plexus cells in the capsule contains various nutrient molecules such as growth factors and signal molecules, and these mixed components can help the patient maintain the healthy activity of the dopamine nerve cells.

Porcine brain cells are encapsulated into capsules with alginate extracted from seaweed, each of which is approximately 0.5 mm in diameter and contains approximately 1000 pig cells. Due to the special permeability of seaweed salt, growth factors secreted by choroid plexus cells can penetrate the capsule and flow to the surrounding brain tissue, but the patient's immune cells can not flow into the capsule to find and attack allogeneic pig cells, so there is no need to take anti-immunological rejection during the operation.
