Spinal cord injury (SCI) has a major impact on affected patients due to its pathological consequences and absence of capacity for self-repair. Currently available therapies are unable to restore lost neural functions. Thus, there is a pressing need to develop novel treatments that will promote functional repair after SCI. Several experimental approaches have been explored to tackle SCI, including the combination of stem cells and 3D bioprinting. Implanted multipotent stem cells with self-renewing capacity and the ability to differentiate to a diversity of cell types are promising candidates for replacing dead cells in injured sites and restoring disrupted neural circuits. However, implanted stem cells need protection from the inflammatory agents in the injured area and support to guide them to appropriate differentiation. Not only are 3D bioprinted scaffolds able to protect stem cells, but they can also promote their differentiation and functional integration at the site of injury. In this review, we showcase some recent advances in the use of stem cells for the treatment of SCI, different types of 3D bioprinting methods, and the combined application of stem cells and 3D bioprinting technique for effective repair of SCI.

Through retrospective analysis of the literature on the cell repair of spinal cord injury worldwide, it is found that the mechanism of cell transplantation repairing spinal cord injury is mainly to replace damaged neurons, protect host neurons, prevent apoptosis, promote axonal regeneration and synapse formation, promote myelination, and secrete trophic factors or growth factors to improve microenvironment. A variety of cells are used to repair spinal cord injury. Stem cells include multipotent stem cells, embryonic stem cells, and induced pluripotent stem cells. The multipotent stem cells are mainly various types of mesenchymal stem cells and neural stem cells. Non-stem cells include olfactory ensheathing cells and Schwann cells. Transplantation of inhibitory interneurons to alleviate neuropathic pain in patients is receiving widespread attention. Different types of cell transplantation have their own advantages and disadvantages, and multiple cell transplantation may be more helpful to the patient’s functional recovery. These cells have certain effects on the recovery of neurological function and the improvement of complications, but further exploration is needed in clinical application. The application of a variety of cell transplantation, gene technology, bioengineering and other technologies has made the prospect of cell transplantation more extensive. There is a need to find a safe and effective comprehensive treatment to maximize and restore the patient’s performance.

Object The authors describe a method for percutaneous transplantation of human umbilical cord blood (hUCB)–derived multipotent stem cells (MSCs) under fluoroscopic guidance. The investigators then tested whether percutaneous transplantation of hUCB-derived MSCs improved neurological functional recovery after acute spinal cord injury (SCI). Methods The authors induced SCI in 10 dogs by percutaneous balloon compression. The 10 injured dogs were assigned randomly to the following groups (2 dogs each): Group 1, evaluated 2 weeks after sham transplantation; Group 2, evaluated 2 weeks after transplantation; Group 3, evaluated 4 weeks after sham transplantation; Group 4, evaluated 4 weeks after transplantation; and Group 5, evaluated 4 weeks after multispot transplantations. The dogs with sham transplantation (Groups 1 and 3) received the same volume of saline, as a control. A spinal needle was advanced into the spinal canal, and the investigators confirmed that the end of the spinal needle was located in the ventral part of spinal cord parenchyma by using contrast medium under fluoroscopic guidance. The hUCB-derived MSCs were transplanted into the cranial end of the injured segment in 6 injured dogs at 7 days after SCI. Results Two dogs in Group 2 showed no improvement until 2 weeks after transplantation. Three of 4 dogs (Groups 4 and 5) that received cellular transplants exhibited gradual improvement in hindlimb locomotion from 3 weeks after cell transplantation. The CM-DiI–labeled hUCB-derived MSCs were observed in the spinal cord lesions at 4 weeks posttransplantation and exerted a significant beneficial effect by reducing cyst and injury size. The transplanted cells were positive for NeuN, glial fibrillary acidic protein, and von Willebrand factor. Conclusions The percutaneous transplantation technique described here can be easily performed, and it differs from previous techniques by avoiding surgical exposure and allowing cells to be more precisely transplanted into the spinal cord. This technique has many potential applications in the treatment of human SCI by cell transplantation. The results also suggest that transplantation of hUCB-derived MSCs may have therapeutic effects that decrease cavitation for acute SCI.

Abstract BackgroundSignal transducer and activator of transcription protein 3 (STAT3) is expressed in neural stem cells (NSCs), and some studies have shown that STAT3 is involved in regulating NSC differentiation. However, the possible molecular mechanism and the role of STAT3 in spinal cord injury (SCI) are unknown. Thus, in the present study, we identified possible molecular mechanisms by which STAT3 regulates NSC differentiation in vitro and investigated the potential therapeutic effect of transplanting STAT3-silenced NSCs in rat SCI models in vivo.MethodsIn vitro, NSCs were divided into the following three groups: control, control shRNA, and STAT3-shRNA lentivirus groups. NSCs in each treatment group were examined for neuronal differentiation via immunofluorescence, and Western blot analysis was used to investigate the possible molecular mechanisms. In vivo, the rats were divided into four groups that underwent laminectomy and complete spinal cord transection accompanied by transplantation of control-shRNA-treated or STAT3-shRNA-treated NSCs at the injured site. Spinal cord-evoked potentials and the Basso-Beattie-Bresnahan score were used to examine functional recovery after SCI. Axonal regeneration and tissue repair were assessed via retrograde tracing using Fluorogold, hematoxylin-eosin staining and immunofluorescence.ResultsKnockdown of STAT3 promoted neuronal differentiation in NSCs and mechanistic target of mammal rapamycin (mTOR) activation in vitro, and transplantation of STAT3-RNAi-treated NSCs enhanced rat functional recovery and tissue repair, as well as neuronal differentiation of the transplanted NSCs in vivo.ConclusionsWe have provided in vitro and in vivo evidence that STAT3 is a negative regulator of NSC neuronal differentiation. Transplantation of STAT3-inhibited NSCs appears to be a promising potential strategy for enhancing the benefit of NSC-mediated regenerative cell therapy for SCI.
