Abstract
There has been a growing interest in the potential of stem cell transplantation as therapy for pediatric brain injuries. Studies in pre-clinical models of pediatric brain injury such as Traumatic Brain Injury (TBI) and neonatal hypoxia-ischemia (HI) have contributed to our understanding of the roles of endogenous stem cells in repair processes and functional recovery following brain injury, and the effects of exogenous stem cell transplantation on recovery from brain injury. Although only a handful of studies have evaluated these effects in models of pediatric TBI, many studies have evaluated stem cell transplantation therapy in models of neonatal HI which has a considerable overlap of injury pathology with pediatric TBI. In this review, we have summarized data on the effects of stem cell treatments on histopathological and functional outcomes in models of pediatric brain injury. Importantly, we have outlined evidence supporting the potential for stem cell transplantation to mitigate pathology of pediatric TBI including neuroinflammation and white matter injury, and challenges that will need to be addressed to incorporate these therapies to improve functional outcomes following pediatric TBI.

Abstract
OBJECTIVES This study aimed to explore cytokine alterations following pediatric sports-related concussion (SRC) and whether a specific cytokine profile could predict symptom burden and time to return to sports (RTS). SETTING Sports Medicine Clinic. PARTICIPANTS Youth ice hockey participants (aged 12-17 years) were recruited prior to the 2013-2016 hockey season. DESIGN Prospective exploratory cohort study. MAIN MEASURE Following SRC, saliva samples were collected and a Sport Concussion Assessment Tool version 3 (SCAT3) was administered within 72 hours of injury and analyzed for cytokines. Additive regression of decision stumps was used to model symptom burden and length to RTS based on cytokine and clinical features. RRelieFF feature selection was used to determine the predictive value of each cytokine and clinical feature, as well as to identify the optimal cytokine profile for the symptom burden and RTS. RESULTS Thirty-six participants provided samples post-SRC (81% male; age 14.4 ± 1.3 years). Of these, 10 features, sex, number of previous concussions, and 8 cytokines, were identified to lead to the best prediction of symptom severity (r = 0.505, P = .002), while 12 cytokines, age, and history of previous concussions predicted the number of symptoms best (r = 0.637, P < .001). The prediction of RTS led to the worst results, requiring 21 cytokines, age, sex, and number of previous concussions as features (r = -0.320, P = .076). CONCLUSIONS In pediatric ice hockey participants following SRC, there is evidence of saliva cytokine profiles that are associated with increased symptom burden. However, further studies are needed.

Abstract
Hypoxic preconditioning is a well-known strategy to improve the survival and therapeutic potential of stem cells against various challenges including hemodynamic and neurohormonal modulations. However, the mechanism involved in hypoxia-induced benefits on stem cells is still ambiguous. In pathological hypertension, the elevation of the neurohormonal mediator Angiotensin II (Ang II) causes the adverse effects to stem cells. In this study, we investigate the effect and mechanism of action of short term hypoxia-inducible miRNA in suppressing the effects of AngII on stem cells. According to the results obtained, Ang II affects the normal cell cycle and triggers apoptosis in rADSCs with a corresponding increase in the expression of cell death-inducing p53 target 1 (CDIP1) protein. However, the short term hypoxia-inducible miRNA-miR-210-3p was found to target CDIP1 and reduce their levels upon the Ang II challenge. CDIP1 induces stress-mediated apoptosis involving the extrinsic apoptosis pathway via Bid/Bax/cleaved caspase3 activation. Administration of mimic miR-210-3p targets CDIP1 mRNA by binding to the 3' UTR region as confirmed by dual luciferase assay and also reduced Ang II-induced mitochondrial ROS accumulation as analyzed by MitoSOX staining. Moreover, the present study demonstrates the mechanism of miR-210-3p in the regulation of Ang II-induced CDIP1-associated apoptotic pathway in rADSCs.

Abstract
Neonatal hypoxic-ischemic encephalopathy is a serious neurological disease, often resulting in long-term neurodevelopmental disorders among surviving children. However, whether these neurodevelopmental issues can be passed to offspring remains unclear. The right common carotid artery of 7-day-old parental-generation rats was subjected to permanent ligation using a vessel electrocoagulator. Neonatal hypoxic-ischemic rat models were established by subjecting the rats to 8% O2–92% N2 for 2 hours. The results showed that 24 hours after hypoxia and ischemia, pathological damage, cerebral atrophy, liquefaction, and impairment were found, and Zea-Longa scores were significantly increased. The parental-generation rats were propagated at 3 months old, and offspring were obtained. No changes in the overall brain structures of these offspring rats were identified by magnetic resonance imaging. However, the escape latency was longer and the number of platform crossings was reduced among these offspring compared with normal rats. These results indicated that the offspring of hypoxic-ischemic encephalopathy model rats displayed cognitive impairments in learning and memory. This study was approved by the Animal Care & Welfare Committee of Kunming Medical University, China in 2018 (approval No. kmmu2019072).

CKLF1 Aggravates Focal Cerebral Ischemia Injury at Early Stage Partly by Modulating Microglia/Macrophage Toward M1 Polarization Through CCR4. Cell Mol Neurobiol 2019; 39:651-669.

Abstract
CKLF1 is a chemokine with increased expression in ischemic brain, and targeting CKLF1 has shown therapeutic effects in cerebral ischemia model. Microglia/macrophage polarization is a mechanism involved in poststroke injury expansion. Considering the quick and obvious response of CKLF1 and expeditious evolution of stroke lesions, we focused on the effects of CKLF1 on microglial/macrophage polarization at early stage of ischemic stroke (IS). The present study is to investigate the CKLF1-mediated expression of microglia/macrophage phenotypes in vitro and in vivo, discussing the involved pathway. Primary microglia culture was used in vitro, and mice transient middle cerebral artery occlusion (MCAO) model was adopted to mimic IS. CKLF1 was added to the primary microglia for 24 h, and we found that CKLF1 modulated primary microglia skew toward M1 phenotype. In mice transient IS model, CKLF1 was stereotactically microinjected to the lateral ventricle of ischemic hemisphere. CKLF1 aggravated ischemic injury, accompanied by promoting microglia/macrophage toward M1 phenotypic polarization. Increased expression of pro-inflammatory cytokines and decreased expression of anti-inflammatory cytokines were observed in mice subjected to cerebral ischemia and administrated with CKLF1. CKLF1-/- mice were used to confirm the effects of CKLF1. CKLF1-/- mice showed lighter cerebral damage and decreased M1 phenotype of microglia/macrophage compared with the WT control subjected to cerebral ischemia. Moreover, NF-κB activation enhancement was detected in CKLF1 treatment group. Our results demonstrated that CKLF1 is an important mediator that skewing microglia/macrophage toward M1 phenotype at early stage of cerebral ischemic injury, which further deteriorates followed inflammatory response, contributing to early expansion of cerebral ischemia injury. Targeting CKLF1 may be a novel way for IS therapy.

Abstract
Myelin is a lipid-rich multilamellar membrane that wraps around long segments of neuronal axons and it increases the conduction of action potentials, transports the necessary trophic support to the neuronal axons, and reduces the energy consumed by the neuronal axons. Together with axons, myelin is a prerequisite for the higher functions of the central nervous system and complex forms of network integration. Myelin impairments have been suggested to lead to neuronal dysfunction and cognitive decline. Accumulating evidence, including brain imaging and postmortem and genetic association studies, has implicated myelin impairments in Alzheimer's disease (AD). Increasing data link myelin impairments with amyloid-β (Aβ) plaques and tau hyperphosphorylation, which are both present in patients with AD. Moreover, aging and apolipoprotein E (ApoE) may be involved in the myelin impairments observed in patients with AD. Decreased neuronal activity, increased Aβ levels, and inflammation further damage myelin in patients with AD. Furthermore, treatments that promote myelination contribute to the recovery of neuronal function and improve cognition. Therefore, strategies targeting myelin impairment may provide therapeutic opportunities for patients with AD.

Abstract
Hypoxic-ischemic encephalopathy (HIE) is a complex condition which is associated with high mortality and morbidity. However, few promising treatments for HIE exist. In the present study, the central objective was to identify the therapeutic effect of pilose antler polypeptides (PAP) on HIE in rats. Sprague-Dawley (SD) rats (14 days old) were used and divided into three groups, including control group, hypoxic-ischemia (HI) group and PAP group. After 21 days of treatment, locomotor activity was improved in PAP-treated rats, brain atrophy was decreased and cerebral edema was mitigated to some extent. Real-time quantitative polymerase chain reaction (RT-qPCR) analysis indicated that PAP administration decreased the expressions of inflammatory cytokines and apoptosis genes in hippocampus compared with HI group. Furthermore, the mRNA expressions of genes related to neurotrophic factors were significantly increased in the hippocampus. In addition, the expressions of oxidative stress markers were all down-regulated after PAP administration. Moreover, PAP up-regulated both the mRNA and protein levels of SDF1 and CXCR4, which may activate the SDF1/CXCR4 axis to moderate brain injury. These results suggest that PAP may be potentially used in the treatment of HIE.

Abstract
Neonatal hypoxic-ischemic encephalopathy continues to be a significant cause of death or neurodevelopmental delays despite standard use of therapeutic hypothermia. The use of stem cell transplantation has recently emerged as a promising supplemental therapy to further improve the outcomes of infants with hypoxic-ischemic encephalopathy. After the injury, the brain releases several chemical mediators, many of which communicate directly with stem cells to encourage mobilization, migration, cell adhesion and differentiation. This manuscript reviews the biomarkers that are released from the injured brain and their interactions with stem cells, providing insight regarding how their upregulation could improve stem cell therapy by maximizing cell delivery to the injured tissue.
