    Adipose-derived stromal cells enhance auditory neuron survival in an animal model of sensory hearing loss.
    Cytotherapy 2017 Aug 14. Epub 2017 Aug 14.
    Department of Oto-Rhino-Laryngology, Head and Neck Surgery, Carl von Ossietzky-University, Oldenburg, Germany. Electronic address:
    Background: A cochlear implant (CI) is an electronic prosthesis that can partially restore speech perception capabilities. Optimum information transfer from the cochlea to the central auditory system requires a proper functioning auditory nerve (AN) that is electrically stimulated by the device. In deafness, the lack of neurotrophic support, normally provided by the sensory cells of the inner ear, however, leads to gradual degeneration of auditory neurons with undesirable consequences for CI performance.

    Self-organization process in newborn skin organoid formation inspires strategy to restore hair regeneration of adult cells.
    Proc Natl Acad Sci U S A 2017 Aug 10. Epub 2017 Aug 10.
    Department of Pathology, Keck School of Medicine, University of Southern California, Los Angeles, CA 90033;
    Organoids made from dissociated progenitor cells undergo tissue-like organization. This in vitro self-organization process is not identical to embryonic organ formation, but it achieves a similar phenotype in vivo. This implies genetic codes do not specify morphology directly; instead, complex tissue architectures may be achieved through several intermediate layers of cross talk between genetic information and biophysical processes.

    Evolution and Development of the Inner Ear Efferent System: Transforming a Motor Neuron Population to Connect to the Most Unusual Motor Protein via Ancient Nicotinic Receptors.
    Front Cell Neurosci 2017 24;11:114. Epub 2017 Apr 24.
    Department of Biology, University of IowaIowa, IA, USA.
    All craniate chordates have inner ears with hair cells that receive input from the brain by cholinergic centrifugal fibers, the so-called inner ear efferents (IEEs). Comparative data suggest that IEEs derive from facial branchial motor (FBM) neurons that project to the inner ear instead of facial muscles. Developmental data showed that IEEs develop adjacent to FBMs and segregation from IEEs might depend on few transcription factors uniquely associated with IEEs. Read More

    Pretrimmed versus Direct Nonshaven Follicular Unit Extraction.
    Plast Reconstr Surg Glob Open 2017 Mar 16;5(3):e1261. Epub 2017 Mar 16.
    Dana Plastic Surgery Clinic, Gangnam-gu, Seoul, Korea.
    Background: Shaving the donor area is one of the major deterrents preventing hair transplant patients from selecting follicular unit extraction (FUE). A minimal shaved donor area is possible in strip surgery, but the strip method is not applicable if the patient wishes to avoid a linear donor scar, wishes to minimize postoperative pain, or has insufficient scalp laxity. In these cases, nonshaven FUE (NS-FUE) is potentially a very good choice. Read More

    Possible damage to immune-privileged sites in natural killer cell therapy in cancer patients: side effects of natural killer cell therapy.
    Immunotherapy 2017 Mar;9(3):281-288
    Shiraz Institute for Cancer Research, Shiraz University of Medical Sciences, Shiraz, Iran.
    Natural killer (NK) cells target the cells losing MHC-I in cancer, a phenotype that is similar to certain cells in immune-privileged sites whose milieus are separated from peripheral blood. NK cells are reported to be quantitatively and qualitatively different in immune-privileged sites from those cytotoxic ones in the blood. We hypothesize that cytotoxic and expanded NK cells induced in cancer patients may be turned into pathogenic factors if they enter immune-privileged microenvironments in susceptible individuals, such as, patients with brain cancer or a blood-brain barrier dysfunction.

    Endogenous dermal stem cells (DSCs) reside in the adult hair follicle mesenchyme and can be isolated and grown in vitro as self-renewing colonies called skin-derived precursors (SKPs). Following transplantation into skin, SKPs can generate new dermis and reconstitute the dermal papilla and connective tissue sheath, suggesting they could have important therapeutic value for the treatment of skin disease (alopecia) or injury. Controlled cell culture processes must be developed to efficiently and safely generate sufficient stem cell numbers for clinical use. Read More
