Biostage Cellframe Technology for Organ Regeneration - YouTube - 0 views

  •  
    In order to improve the surgical outcome of these procedures and enhance patient quality of life, new and better tools are needed for esophageal reconstruction. Biostage is working on a new regenerative technology to address esophageal cancer through their pioneer Cellframe Technology. Two weeks before the surgery, stem cells are harvested from patient abdominal adipose tissue and allowed to incubate with a biocompatible esophageal implant. These cells interact and adhere to the implant and are able to respond to signals for regeneration once inside the patient, potentially restoring both the structural and functional integrity of the esophagus. These new approaches to organ implants could revolutionize resectional surgery by providing patients with functional replacements derived from their own cells.

Retroviral influence on human embryonic development - 0 views

  •  
    The most recent human retroviral infections leading to germ line integration took place with a subgroup of human endogenous retroviruses called HERVK(HML-2). The human genome contains ~90 copies of these viral genomes, which might have infected human ancestors as recently as 200,000 years ago. HERVs do not produce infectious virus: not only is the viral genome silenced - no mRNAs are produced - but they are littered with lethal mutations that have accumulated over time. A recent study revealed that HERVK mRNAs are produced during normal human embryogenesis. Viral RNAs were detected beginning at the 8-cell stage, through epiblast cells in preimplantation embryos, until formation of embryonic stem cells (illustrated). At this point the production of HERVK mRNA ceases. Viral capsid protein was detected in blastocysts, and electron microscopy revealed the presence of virus-like particles similar to those found in reconstructed HERVK particles. These results indicate that retroviral proteins and particles are present during human development, up until implantation.

Regenerative medicine approach improves muscle strength, function in leg injuries; Deri... - 0 views

  •  
    Damaged leg muscles grew stronger and showed signs of regeneration in three out of five men whose old injuries were surgically implanted with extracellular matrix derived from pig bladder, according to a new study. Early findings are from a human trial of the process as well as from animal studies.

Hearing quality restored with bionic ear technology used for gene therapy: Re-growing a... - 0 views

  •  
    Researchers have for the first time used electrical pulses delivered from a cochlear implant to deliver gene therapy, thereby successfully regrowing auditory nerves. The research also heralds a possible new way of treating a range of neurological disorders, including Parkinson's disease, and psychiatric conditions such as depression through this novel way of delivering gene therapy.

My Husband and I Are Both Carriers for a Jewish Genetic Disease. Here's How We Had Kids... - 0 views

  •  
    I'm a carrier of a Jewish genetic disease. With that, here's my journey, which will explain why I'm so passionate about advocating for JScreen-a national organization that focuses on education and screening for Jewish genetic diseases.
