Dopaminergic progenitors generated by small molecule approach survived, integrated, and promoted functional recovery in (6-OHDA) mouse model of Parkinson's disease. J Neurol Sci 2024; 465:123188. [PMID: 39178824 DOI: 10.1016/j.jns.2024.123188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 08/13/2024] [Accepted: 08/18/2024] [Indexed: 08/26/2024]
Abstract
Parkinson's disease (PD) is a neurodegenerative disorder resulting from the loss of dopamine-producing neurons in the brain, causing motor symptoms like tremors and stiffness. Although current treatments like medication and deep brain stimulation can alleviate symptoms, they don't address the root cause of neuron loss. Therefore, cell replacement therapy emerges as a promising treatment strategy. However, the generation of engraftable dopaminergic (DA) cells in clinically relevant quantities is still a challenge. Recent advances in cell reprogramming technologies open up vast possibilities to produce patient-specific cells of a desired type in therapeutic quantities. The main cell reprogramming strategies involve the enforced expression of individual or sets of genes through viral transduction or transfection, or through small molecules, known as the chemical approach, which is a much easier and safer method. In our previous studies, using a small molecule approach (combinations of epigenetic modifiers and SMAD inhibitors such asDorsomorphin and SB431542), we have been able to generate DA progenitors from human mesenchymal stem cells (hMSCs). The aim of this study was to further improve the method for the generation of DA progenitors and to test their therapeutic effect in an animal model of Parkinson's. The results showed that the addition of an autophagy enhancer (AE) to our DA cell induction protocol further increased the yield of DA progenitor cells. The results also showed that DA progenitors transplanted into the mouse model of PD survived, integrated, and improved PD motor symptoms. These data suggest that chemically-produced DA cells can be very promising and safe cellular therapeutics for PD.

[PMID: 37545752 PMCID: PMC10401416 DOI: 10.4252/wjsc.v15.i7.665] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 03/17/2023] [Accepted: 04/10/2023] [Indexed: 07/25/2023] Open
Abstract
In recent years, mesenchymal stem cells (MSC) have been considered the most effective source for regenerative medicine, especially due to released soluble paracrine bioactive components and extracellular vesicles. These factors, collectively called the secretome, play crucial roles in immunomodulation and in improving survival and regeneration capabilities of injured tissue. Recently, there has been a growing interest in the secretome released by retinal cytotypes, especially retinal pigment epithelium and Müller glia cells. The latter trophic factors represent the key to preserving morphofunctional integrity of the retina, regulating biological pathways involved in survival, function and responding to injury. Furthermore, these factors can play a pivotal role in onset and progression of retinal diseases after damage of cell secretory function. In this review, we delineated the importance of cross-talk between MSCs and retinal cells, focusing on common/induced secreted factors, during experimental therapy for retinal diseases. The cross-link between the MSC and retinal cell secretomes suggests that the MSC secretome can modulate the retinal cell secretome and vice versa. For example, the MSC secretome can protect retinal cells from degeneration by reducing oxidative stress, autophagy and programmed cell death. Conversely, the retinal cell secretome can influence the MSC secretome by inducing changes in MSC gene expression and phenotype.

Abstract
Neurodegenerative diseases have different types according to the onset of the disease, the time course, and the underlying pathology. Although the dogma that brain cells cannot regenerate has changed, the normal regenerative process of the brain is usually not sufficient to restore brain tissue defects after different pathological insults. Stem cell therapy and more recently cell reprogramming could achieve success in the process of brain renewal. This review article presents recent advances of stem cell therapies in neurodegenerative diseases and the role of cell reprogramming in the scope of optimizing a confined condition that could direct signaling pathways of the cell toward a specific neural lineage. Further, we will discuss different types of transcriptional factors and their role in neural cell fate direction.

Abstract
Multiple studies have demonstrated the ability of mesenchymal stem cells (MSCs) to differentiate into dopamine-producing cells, in vitro and in vivo, indicating their potential to be used in the treatment of Parkinson’s disease (PD). However, there are discrepancies among studies regarding the optimal time (i.e., passage number) and method for dopaminergic induction, in vitro. In the current study, we compared the ability of early (P4) and later (P40) passaged bone marrow-derived MSCs to differentiate into dopaminergic neurons using two growth-factor-based approaches. A direct dopaminergic induction (DDI) was used to directly convert MSCs into dopaminergic neurons, and an indirect dopaminergic induction (IDI) was used to direct MSCs toward a neuronal lineage prior to terminal dopaminergic differentiation. Results indicate that both early and later passaged MSCs exhibited positive expression of neuronal and dopaminergic markers following either the DDI or IDI protocols. Additionally, both early and later passaged MSCs released dopamine and exhibited spontaneous neuronal activity following either the DDI or IDI. Still, P4 MSCs exhibited significantly higher spiking and bursting frequencies as compared to P40 MSCs. Findings from this study provide evidence that early passaged MSCs, which have undergone the DDI, are more efficient at generating dopaminergic-like cells in vitro, as compared to later passaged MSCs or MSCs that have undergone the IDI.

Abstract
Bone marrow-derived mesenchymal stem cells (BMSCs) and adipose tissue-derived mesenchymal stem cells (ADSCs) are able to differentiate into neuron-like cells when exposed to small molecule compounds, however the specific differences in their neuronal differentiation abilities remain to be fully elucidated. The present study aimed to compare the neuronal differentiation abilities of BMSCs and ADSCs. BMSCs and ADSCs from the same Sprague Dawley rats were isolated and cultured for use. The proliferation capacity was revealed using a cell counting method. Following BMSCs and ADSCs induction by four types of small-molecular compounds, the expression of various neuronal markers and the secretion of several neurotrophic factors were detected by immunofluorescence, western blotting, reverse transcription-quantitative polymerase chain reaction and ELISA. It was demonstrated that the ADSCs exhibited an increased proliferation capacity compared with BMSCs, according to cumulative population doubling analyses. Following a 7-day neuronal induction period, BMSCs and ADSCs exhibited a neuron-like morphology, and were termed neuronal induced (NI)-BMSCs and NI-ADSCs. They expressed neuronal markers including β-tubulin III, microtubule associated protein 2 and choline acetyltransferase. The number of NI-BMSCs that positively expressed the neuronal markers was significantly decreased compared with NI-ADSCs, and the expression and secretion of the neurotrophic factors nerve growth factor and 3′-nucleotidase in NI-BMSCs were additionally decreased compared with NI-ADSCs. The findings of the present study indicated that the neuronal differentiation abilities and neurotrophic factor secretion abilities of ADSCs were increased compared with BMSCs. ADSCs may therefore act as efficient candidates in cell transplantation therapy for diseases and injuries of the nervous system.

Abstract
Discoveries in recent years have suggested that some tissue specific adult stem cells in mammals might have the ability to differentiate into cell types from different germ layers. This phenomenon has been referred to as stem cell transdifferentiation or plasticity. Despite controversy, the current consensus holds that transdifferentiation does occur in mammals, but only within a limited range. Understanding the mechanisms that underlie the switches in phenotype and development of the methods that will promote such type of conversions can open up endless possibilities for regenerative medicine. Epigenetic control contributes to various processes that lead to cellular plasticity and DNA and histone covalent modifications play a key role in these processes. Recently, we have been able to convert human mesenchymal stem cells (hMSCs) into neural-like cells by exposing cells to epigenetic modifiers and neural inducing factors. The goal of this study was to investigate the stability and plasticity of these transdifferentiated cells. To this end, neurally induced MSCs (NI-hMSCs) were exposed to adipocyte inducing factors. Grown for 24-48 h in fat induction media NI-hMSCs reversed their morphology into fibroblast-like cells and regained their proliferative properties. After 3 weeks approximately 6% of hMSCs differentiated into multilocular or plurivacuolar adipocyte cells that demonstrated by Oil Red O staining. Re-exposure of these cultures or the purified adipocytes to neural induction medium induced the cells to re-differentiate into neuronal-like cells. These data suggest that cell plasticity can be manipulated by the combination of small molecule modulators of chromatin modifying enzymes and specific cell signaling pathways.

Abstract
Recently, using the chemical genetics approach for cell reprogramming, via the combination of small molecule modulators of chromatin modifying enzymes, specific SMAD signaling pathways, and cyclic adenosine monophosphate levels, we have been able to generate neuronallike cells predominantly positive to mature neuronal and dopaminergic markers. This study aimed to characterize further the dopaminergic properties of neurally induced (NI) human bone marrow-derived mesenchymal stem cells (hMSCs) and to determine whether addition of sonic hedgehog (SHH)/fibroblast growth factor 8 (FGF8) to NI medium could promote further dopaminergic maturation. Dopaminergic differentiation was evaluated by immunocytochemistry, reverse transcription-polymerase chain reaction, Western blot, and enzyme-linked immunosorbent assay. Results demonstrated that release of dopamine by NI-hMSCs differentiated with SMAD inhibitor supplementation significantly increased from picogram to nanogram levels, with a tendency of further increase when supplemented by SHH/FGF8. Direct generation of dopaminergic cells from adult hMSCs by using this reprogramming approach may have significant implications for understanding the mechanism underlying cell plasticity and may open new potentialities for cell replacement therapies.
