Conclusion:Our findings demonstrate that rTMS treatment and hMSC transplantation could synergistically create a favorable microenvironment for cell survival within the PD rat brain, through alteration of soluble factors such as neurotrophic/growth factors and anti-/pro-inflammatory cytokines related to neuronal protection or repair, with preservation of DA neurons and improvement of motor functions.

Publication date: Available online 21 January 2020Source: Biochimica et Biophysica Acta (BBA) - Molecular Cell ResearchAuthor(s): Takashi Hoshiba, Natsumi YokoyamaAbstractThe regulation of stem cell differentiation is key for muscle tissue engineering and regenerative medicine. To this end, various substrates mimicking the native extracellular matrix (ECM) have been developed with consideration of the mechanical, topological, and biochemical properties. However, mimicking the biochemical properties of the native ECM is difficult due to its compositional complexity. To develop substrates that mimic the native ECM and its bi...

Delivery of exosomes derived from stem cell populations has been demonstrated to improve recovery from injury in numerous studies and human applications. The interesting aspect of this demonstration in stroke recovery in pigs is that exosomes from neural stem cells provoke greater functional recovery without improving some of the structural changes that are normally associated with greater mortality and loss of function. Researchers have presented brain imaging data for a new stroke treatment that supported full recovery in swine, modeled with the same pattern of neurodegeneration as seen in humans with severe str...

AbstractSkin repair and reconstruction are important after severe wound and trauma. Keratinocyte stem cells (KSCs) in the basal layer of the epidermis can regrow the stratified epidermis but are almost depleted after skin injury. Thus, generating enough KSCs is indispensable for skin regeneration. Pluripotent stem cells such as ESC and iPSC can differentiate into KSCs, but their applications are challenged by ethical issues and risks of tumor formation. Lineage reprogramming from one cell type into another one makes it feasible to generate the desired cell type. Here, we develop a method to convert human fibroblasts into i...

The J.P. Morgan Healthcare conference runs every year in San Francisco, a big draw for the biotech industry, and many organizations take the opportunity to host events at the same time. Among these, the SENS Research Foundation has for the past few years hosted a pitch day in which biotech companies in the longevity industry, largely startups, present to that portion of the Bay Area investor community interested in funding the treatment of aging as a medical condition. I was there to present on progress at Repair Biotechnologies, and took some notes on the other companies as they talked about their work. Kimera Labs ...

Conclusion: It can be concluded that A/S similar to TGF ‑β1 is able to facilitate the chondrogenicdifferentiation of hADSCs and do not have adverse effects of TGF ‑β1. Thus, TGF‑β1 can be replacedby A/S in the field of tissue engineering.

Negative regulators of adult neurogenesis are of particular interest as targets to enhance neuronal repair, but few have yet been identified. Planarians can regenerate their entire CNS using pluripotent adult stem cells, and this process is robustly regulated to ensure that new neurons are produced in proper abundance. Using a high-throughput pipeline to quantify brain chemosensory neurons, we identify the conserved tyrosine kinasetec-1 as a negative regulator of planarian neuronal regeneration.tec-1RNAi increased the abundance of several CNS and PNS neuron subtypes regenerated or maintained through homeostasis, without af...
