| 9 | Differentiation and functional connectivity of fetal tectal transplants显示文摘Data from studies analyzing the differentiation and functional connectivity of embryo nic neural tissue grafted into the mammalian nervous system has led to the clinical testing of the fetal graft approach in patients with neurodegenerative disease.While some success has been achieved,ethical concerns have led to a search for alternative therapeutic strategies,mostly exploring the use of neural precursors or neurons derived from pluripotent stem cells to replace damaged host neurons and restore lost circuitries.These more recent studies address questions of graft viability,differentiation,and connectivity similar to those posed by researchers in earlier fetal transplant work,thus reviews of the fetal graft literature may inform and help guide ongoing research in the stem cell/organoid field.This brief review describes some key observations from research into the transplantation of neural tissue into the rat visual syste m,focusing on grafts of the fetal supe rior colliculus(tectal grafts) into neonatal or adult hosts.In neonate hosts,grafts quickly develop connections with the underlying host mid b rain and attain a morphology typical of mature grafts by about 2 weeks.G rafts consistently contain numerous localized regions which,based on neurofibrillar staining,neuronal morphology(Golgi),neurochemistry,receptor expression,and glial architecture,are homologous to the stratum griseum supe rficiale of normal superior colliculus.These localized 'patches' are also seen after explant culture and when donor tectal tissue is dissociated and reaggregated prior to transplantation.In almost all circumstances,host retinal innervation is restricted to these localized patches,but only those that are located adjacent to the graft surfa ce.Synapses are formed and there is evidence of functional drive.The only exception occurs when Schwann cells are added to dissociated tecta prior to reaggregation.In these co-grafts,the peripheral glia appear to compete with local target fa ctors and host retinal ingrowth is more widespread.Other afferent systems(e.g.,host co rtex,serotonin) show different patterns of innervation.The host cortical input originates more from extrastriate regions and establishes functional excitato ry synapses with grafted neurons.Finally,when grafted into optic tra ct lesions in adult rat hosts,spontaneously regrowing host retinal axons retain the capacity to selectively innervate the localized patches in embryonic tectal grafts,showing that the specific affinities between adult retinal axons and their targets are not lost during regeneration.While the research described here provides some pertinent information about development and plasticity in visual pathways,a more general aim is to highlight how the review of the extensive fetal graft lite rature may aid in an appreciation of the positive(and negative) fa ctors that influence survival,differentiation,connectivity and functionality of engineered cells and organoids transplanted into the central nervous system. | Alan R.Harvey | 2023 | Neural Regeneration Research2023,18,11: | 0 |
| 10 | Effects of amyloid precursor protein peptide APP96-110,alone or with human mesenchymal stromal cells,on recovery after spinal cord injury显示文摘Delivery of a peptide(APP96-110),derived from amyloid precursor protein(APP),has been shown to elicit neuroprotective effects following cerebral stroke and traumatic brain injury.In this study,the effect of APP96-110 or a mutant version of this peptide(mAPP96-110)was assessed following moderate(200 kdyn,(2 N))thoracic contusive spinal cord injury(SCI)in adult Nude rats.Animals received a single tail vein injection of APP96-110 or mAPP96-110 at 30 minutes post-SCI and were then assessed for functional improvements over the next 8 weeks.A cohort of animals also received transplants of either viable or non-viable human mesenchymal stromal cells(hMSCs)into the SC lesion site at one week post-injury to assess the effect of combining intravenous APP96-110 delivery with hMSC treatment.Rats were perfused 8 weeks post-SCI and longitudinal sections of spinal cord analyzed for a number of factors including hMSC viability,cyst size,axonal regrowth,glial reactivity and macrophage activation.Analysis of sensorimotor function revealed occasional significant differences between groups using Ladderwalk or Ratwalk tests,however there were no consistent improvements in functional outcome after any of the treatments.mAPP96-110 alone,and APP96-110 in combination with both viable and non-viable hMSCs significantly reduced cyst size compared to SCI alone.Combined treatments with donor hMSCs also significantly increased βIII tubulin^(+),glial fibrillary acidic protein(GFAP^(+))and laminin+expression,and decreased ED1^(+)expression in tissues.This preliminary study demonstrates that intravenous delivery of APP96-110 peptide has selective,modest neuroprotective effects following SCI,which may be enhanced when combined with hMSC transplantation.However,the effects are less pronounced and less consistent compared to the protective morphological and cognitive impact that this same peptide has on neuronal survival and behaviour after stroke and traumatic brain injury.Thus while the efficacy of a particular therapeutic approach in one CNS injury model may provide justification for its use in other neurotrauma models,similar outcomes may not necessarily occur and more targeted approaches suited to location and severity are required.All animal experiments were approved by The University of Western Australia Animal Ethics Committee(RA3/100/1460)on April 12,2016. | Stuart I.Hodgetts Sarah J.Lovett D.Baron-Heeris A.Fogliani Marian Sturm C.Van den Heuvel Alan R.Harvey | 2022 | Neural Regeneration Research2022,17,6: | 0 |
