Spinal cord injury research different types of cells. The hope is that stem cells transplanted into an injured area of the spinal cord will allow neuroregeneration. Types of cells being researched for use in SCI include embryonic stem cells, neural stem cells, mesenchymal stem cells, olfactory ensheathing cells, Schwann cells, activated macrophages, and induced pluripotent stem cells. When stem cells are injected in the area of damage in the spinal cord, they secrete neurotrophic factors, and these factors help neurons and blood vessels to grow, thus helping repair the damage. It is also necessary to recreate an environment in which stem cells will grow.
Human Endogenous Retrovirus-W in the human haploid genome with 70 gag, 100 pro, and 30 env regions. With in vitro transcription techniques three suggested ORFs on chromosome 3 (gag), 6 (pro) and 7 (env) were detected and further analyzed revealing that the ORF on chromosome 7q21.2 uniquely encoded a glycosylated Env protein. Performing RealTime RT-PCR on adrenal gland, bone marrow, cerebellum, whole brain, fetal brain, fetal liver, heart, kidney, liver, lung, placenta, prostate, salivary gland, skeletal muscle, spinal cord, testis, thymus, thyroid gland, trachea, and uterus cells revealed 22 complete HERV-W families on chromosomes 1–3, 5–8, 10–12, 15, 19 and X.
