Axonal Extensions along Corticospinal Tracts from Transplanted Human Cerebral Organoids. Stem Cell Reports 2020; 15:467-481.

Abstract
The reconstruction of lost neural circuits by cell replacement is a possible treatment for neurological deficits after cerebral cortex injury. Cerebral organoids can be a novel source for cell transplantation, but because the cellular composition of the organoids changes along the time course of the development, it remains unclear which developmental stage of the organoids is most suitable for reconstructing the corticospinal tract. Here, we transplanted human embryonic stem cell-derived cerebral organoids at 6 or 10 weeks after differentiation (6w- or 10w-organoids) into mouse cerebral cortices. 6w-organoids extended more axons along the corticospinal tract but caused graft overgrowth with a higher percentage of proliferative cells. Axonal extensions from 10w-organoids were smaller in number but were enhanced when the organoids were grafted 1 week after brain injury. Finally, 10w-organoids extended axons in cynomolgus monkey brains. These results contribute to the development of a cell-replacement therapy for brain injury and stroke.

Abstract
The motor cortex plays a central role in the control, planning, and execution of voluntary motor commands in mammals. The loss of cortical neurons is a common feature of many neuropathological conditions such as traumatic and ischemic lesions or several neurodegenerative diseases. Cell transplantation presents a promising therapeutic strategy to overcome the limited abilities of axonal regrowth and spontaneous regeneration of the adult central nervous system. In this review, we will present a historical review of brain transplantation and the current state of research in the field of cortical transplantation.

Abstract
Lifelong neurogenesis and incorporation of newborn neurons into mature neuronal circuits operates in specialized niches of the mammalian brain and serves as role model for neuronal replacement strategies. However, to which extent can the remaining brain parenchyma, which never incorporates new neurons during the adulthood, be as plastic and readily accommodate neurons in networks that suffered neuronal loss due to injury or neurological disease? Which microenvironment is permissive for neuronal replacement and synaptic integration and which cells perform best? Can lost function be restored and how adequate is the participation in the pre-existing circuitry? Could aberrant connections cause malfunction especially in networks dominated by excitatory neurons, such as the cerebral cortex? These questions show how important connectivity and circuitry aspects are for regenerative medicine, which is the focus of this review. We will discuss the impressive advances in neuronal replacement strategies and success from exogenous as well as endogenous cell sources. Both have seen key novel technologies, like the groundbreaking discovery of induced pluripotent stem cells and direct neuronal reprogramming, offering alternatives to the transplantation of fetal neurons, and both herald great expectations. For these to become reality, neuronal circuitry analysis is key now. As our understanding of neuronal circuits increases, neuronal replacement therapy should fulfill those prerequisites in network structure and function, in brain-wide input and output. Now is the time to incorporate neural circuitry research into regenerative medicine if we ever want to truly repair brain injury.

Abstract
Transplantation of embryonic cortical tissue for repairing the damaged brain has provided a potential therapy for brain injury and diseases. The grafted tissue can successfully survive and participate in reestablishing the functional neural circuit of the host brain. Transplantation surgery can be combined with fluorescently labeled transgenic mice to evaluate the reconstruction of neuronal network ( Falkner et al., 2016 ) and the repopulation of a subset of cortical cells. By using this approach, we have shown that infiltrating cells from host brain can restore the microglial population in the graft tissue ( Wang et al., 2016 ). This protocol describes the detailed procedure of the transplantation surgery in mice, including establishing a lesion model in the host brain, preparing the embryonic cortical graft, and transplanting the embryonic cortical graft to adult brain.

Abstract
Under appropriate conditions, neural tissues transplanted into the adult mammalian brain can survive, integrate, and function so as to influence the behavior of the host, opening the prospect of repairing neuronal damage, and alleviating symptoms associated with neuronal injury or neurodegenerative disease. Alternative mechanisms of action have been postulated: nonspecific effects of surgery; neurotrophic and neuroprotective influences on disease progression and host plasticity; diffuse or locally regulated pharmacological delivery of deficient neurochemicals, neurotransmitters, or neurohormones; restitution of the neuronal and glial environment necessary for proper host neuronal support and processing; promoting local and long-distance host and graft axon growth; formation of reciprocal connections and reconstruction of local circuits within the host brain; and up to full integration and reconstruction of fully functional host neuronal networks. Analysis of neural transplants in a broad range of anatomical systems and disease models, on simple and complex classes of behavioral function and information processing, have indicated that all of these alternative mechanisms are likely to contribute in different circumstances. Thus, there is not a single or typical mode of graft function; rather grafts can and do function in multiple ways, specific to each particular context. Consequently, to develop an effective cell-based therapy, multiple dimensions must be considered: the target disease pathogenesis; the neurodegenerative basis of each type of physiological dysfunction or behavioral symptom; the nature of the repair required to alleviate or remediate the functional impairments of particular clinical relevance; and identification of a suitable cell source or delivery system, along with the site and method of implantation, that can achieve the sought for repair and recovery.

Abstract
We previously reported that embryonic motor cortical neurons transplanted immediately after lesions in the adult mouse motor cortex restored damaged motor cortical pathways. A critical barrier hindering the application of transplantation strategies for a wide range of traumatic injuries is the determination of a suitable time window for therapeutic intervention. Here, we report that a 1 week delay between the lesion and transplantation significantly enhances graft vascularization, survival, and proliferation of grafted cells. More importantly, the delay dramatically increases the density of projections developed by grafted neurons and improves functional repair and recovery as assessed by intravital dynamic imaging and behavioral tests. These findings open new avenues in cell transplantation strategies as they indicate successful brain repair may occur following delayed transplantation.SIGNIFICANCE STATEMENT Cell transplantation represents a promising therapy for cortical trauma.

Abstract
Transplantation of embryonic cortical tissue is considered as a promising therapy for brain injury. Grafted neurons can reestablish neuronal network and improve cortical function of the host brain. Microglia is a key player in regulating neuronal survival and plasticity, but its activation and dynamics in grafted cortical tissue remain unknown. Using two-photon intravital imaging and parabiotic model, here we investigated the proliferation and source of microglia in the donor region by transplanting embryonic cortical tissue into adult cortex. Live imaging showed that the endogenous microglia of the grafted tissue were rapidly lost after transplantation. Instead, host-derived microglia infiltrated and colonized the graft. Parabiotic model suggested that the main source of infiltrating cells is the parenchyma of the host brain. Colonized microglia proliferated and experienced an extensive morphological transition and eventually differentiated into resting ramified morphology. Collectively, these results demonstrated that donor tissue has little contribution to the activated microglia and host brain controls the microglial population in the graft.

Abstract
Injury to the human central nervous system can lead to devastating consequences due to its poor ability to self-repair. Neural transplantation aimed at replacing lost neurons and restore functional circuitry has proven to be a promising therapeutical avenue. We previously reported in adult rodent animal models with cortical lesions that grafted fetal cortical neurons could effectively re-establish specific patterns of projections and synapses. The current study was designed to provide a detailed characterization of the spatio-temporal in vivo development of fetal cortical transplanted cells within the lesioned adult motor cortex and their corresponding axonal projections. We show here that as early as 2 weeks after grafting, cortical neuroblasts transplanted into damaged adult motor cortex developed appropriate projections to cortical and subcortical targets. Grafted cells initially exhibited characteristics of immature neurons, which then differentiated into mature neurons with appropriate cortical phenotypes where most were glutamatergic and few were GABAergic. All cortical subtypes identified with the specific markers CTIP2, Cux1, FOXP2, and Tbr1 were generated after grafting as evidenced with BrdU co-labeling. The set of data provided here is of interest as it sets biological standards for future studies aimed at replacing fetal cells with embryonic stem cells as a source of cortical neurons.

Abstract
Pluripotent stem-cell-derived neurons constitute an attractive source for replacement therapies, but their utility remains unclear for cortical diseases. Here, we show that neurons of visual cortex identity, differentiated in vitro from mouse embryonic stem cells (ESCs), can be transplanted successfully following a lesion of the adult mouse visual cortex. Reestablishment of the damaged pathways included long-range and reciprocal axonal projections and synaptic connections with targets of the damaged cortex. Electrophysiological recordings revealed that some grafted neurons were functional and responsive to visual stimuli. No significant integration was observed following grafting of the same neurons in motor cortex, or transplantation of embryonic motor cortex in visual cortex, indicating that successful transplantation required a match in the areal identity of grafted and lesioned neurons. These findings demonstrate that transplantation of mouse ESC-derived neurons of appropriate cortical areal identity can contribute to the reconstruction of an adult damaged cortical circuit.

Abstract
Damage to the adult motor cortex leads to severe and frequently irreversible deficits in motor function. Transplantation of embryonic cortical neurons into the damaged adult motor cortex was previously shown to induce partial recovery, but reports on graft efferents have varied from no efferent projections to sparse innervation. Here, we grafted embryonic cortical tissue from transgenic mice overexpressing a green fluorescent protein into the damaged motor cortex of adult mice. Grafted neurons developed efferent projections to appropriate cortical and subcortical host targets, including the thalamus and spinal cord. These projections were not a result of cell fusion between the transplant and the host neurons. Host and transplanted neurons formed synaptic contacts and numerous graft efferents were myelinated. These findings demonstrate that there is substantial anatomical reestablishment of cortical circuitry following embryonic cortex grafting into the adult brain. They suggest that there is an unsuspected potential for neural cell transplantation to promote reconstruction after brain injury.

Abstract
Mechanisms intrinsic to the early cerebral cortex have been implicated in the establishment of cortical area identity. However, the extent to which the cortical protomap contributes to the formation of highly complex intrahemispheric connections remains obscure. Mechanisms by which postmitotic neurons establish correct corticocortical connections later in corticogenesis also remain to be elucidated. Here, we used a new transplantation method, employing donor tissue harvested from enhanced green fluorescent protein-expressing rats, to show that cortical progenitors are regionally specified for connectional potential and that this controls the development of specific intrahemispheric projections. The acquisition of connectional capacity relies on positional cues within the cortical primordium, but is independent of thalamic inputs. In addition, since cortical neurons developing in organotypic slice culture extended axons more prominently into their normal cortical target tissues than into non-target tissues, we suggest that cortical neurons respond to specific signals derived from their cortical targets.
