Direct Reprogramming of Human Astrocytes into Spinal Cord Organoids Facilitating Spinal Cord Regeneration

Project description:Human astrocytes have reported to reprogram into neurons, but they have yet to be induced to three-dimensional (3D) neural tissue for neural organogenesis. Here, we demonstrate a remarkable strategy for 3D organoid generation by direct reprogramming human astrocytes. By combining overexpression OCT4, suppression p53 and small molecules CHIR99021, SB431542, RepSox and Y27632, termed as Op53-CSBRY, we successfully reprogramed human astrocytes into neural ectodermal cells and further induced human 3D-brain organoid. Those organoids can be finally induced into spinal cord organoids by activating FGF, SHH and BMP signaling. The grafts of Human astrocyte derived spinal cord organoids (hADSC-Organs) can survived, differentiated into spinal cord neurons, migrated long distance, formed synaptic connectivity with host neurons, bridged complete injury spinal cord tissue in mice. This method indicates that human astrocytes could be directly triggered neural organogenesis, and may hold a great promising to support local astrocytes in situ organogenesis after brain damages, such as stroke and spinal cord injury.

RNA-Seq of human spinal cord organoids generated in Matrigel and alginate

Project description:This experiment compares the transcriptome profile of human spinal cord organoids generated from iPSCs in Matrigel, 1% alginate hydrogel, or 2% alginate hydrogel. Spinal cord organoids were generated from human iPSCs and then encapsulated in the respective hydrogels before further maturation. Organoids were harvested on days 30, 60, and 90 for each group. In addition to the differences between hydrogel groups, neuronal and glial markers at each time point were also assessed for the development of the organoids.

Harnessing developmental dynamics of spinal cord extracellular matrix improves regenerative potential of spinal cord organoids

Project description:Neonatal spinal cord tissues exhibit remarkable regenerative capabilities as compared to adult spinal cord tissues after injury, but the role of extracellular matrix (ECM) in this process has remained elusive. Here, we found that early developmental spinal cord had higher levels of ECMproteins associated with neural development and axon growth, but fewer inhibitory proteoglycans, compared to those of adult spinal cord. Decellularized spinal cord ECM from neonatal (DNSCM) and adult (DASCM) rabbits preserved these differences. DNSCM promoted proliferation, migration, and neuronal differentiation of neural progenitor cells (NPCs) and facilitated axonal outgrowth and regeneration of spinal cord organoids more effectively than DASCM. Pleiotrophin (PTN) and Tenascin (TNC) inDNSCMwere identified as contributors tothese abilities. Furthermore,DNSCMdemonstrated superior performance as a delivery vehicle forNPCs and organoids in spinal cord injury (SCI)models. This suggests that ECMcues from early development stages might significantly contribute to the prominent regeneration ability in spinal cord.

Unveiling the development specific regenerative potential of spinal cord: insights from extracellular matrix

Project description:Neonatal spinal cord tissues exhibit remarkable regenerative capabilities than adult tissues after injury, but the role of extracellular matrix (ECM) in this process has remained elusive. Here we found that early developmental spinal cord had higher levels of ECM proteins associated with neural development and axon growth, but fewer inhibitory proteoglycans compared to adult spinal cord. Decellularized spinal cord ECM from neonatal (DNSCM) and adult (DASCM) rabbits preserved these differences. DNSCM promoted proliferation, migration, and neuronal differentiation of neural progenitor cells (NPCs), and facilitated axonal outgrowth and regeneration of spinal cord organoids than DASCM. Pleiotrophin (PTN) and Tenascin (TNC) in DNSCM were identified as contributors to these abilities. Furthermore, DNSCM demonstrated superior performance as a delivery vehicle for NPCs and organoids in rats with spinal cord injury (SCI). It suggests that ECM cues from early development stages might significantly contribute to the prominent regeneration ability in spinal cord.

Unveiling the Development Specific Regenerative Potential of Spinal Cord: Insights from Extracellular Matrix

Project description:Neonatal spinal cord tissues exhibit remarkable regenerative capabilities compared to adult tissues following injury. Although some cellular signaling pathways involved in the process have been identified, the specific role of extracellular matrix (ECM) responsible for neonatal spinal cord regeneration has remained elusive. Here we revealed that early developmental spinal cord contained a higher abundance of ECM proteins associated with neural development and axon growth but fewer inhibitory proteoglycans compared to adult spinal cord. Decellularized spinal cord ECM from neonatal (DNSCM) and adult (DASCM) rabbits preserve the major difference of native spinal cord tissues in both stages. Compared to DASCM, DNSCM promoted proliferation, migration, and neuronal differentiation of neural progenitor cells (NPCs), as well as facilitated the long-distance axonal outgrowth and axon regeneration of spinal cord organoids. Pleiotrophin (PTN) and Tenascin (TNC) in DNSCM were identified as contributors to the remarkable neural regeneration ability. Furthermore, DNSCM demonstrated superior performance when used as a delivery vehicle for NPCs and organoids in rats with spinal cord injury (SCI). It suggests that ECM cues derived from different development stage might contribute to the distinct regeneration ability of spinal cord.
