Politis, M. et al. Serotonergic neurons mediate dyskinesia side effects in Parkinson’s patients with neural transplants. Sci. Transl. Med. 2, 38ra46 (2010). I’m partial to 10069. By itself, it may not look great, but I used every part (and no other parts) from five copies to build a 10” tall tree that I can add to our seasonal club layouts. The spiral wing designs used in newer Winter Village sets is also fun to play around with as it allows more variety in terms of fullness. This style really only works for very fat trees that many homes don’t have room for. I do prefer it to the inverted slope style, which tend to look fairly anemic.Hughes, C. S., Postovit, L.

Ang, S.-L. Transcriptional control of midbrain dopaminergic neuron development. Development 133, 3499–506 (2006). Based on the observed FOXA2 expression patterns, we hypothesized that a desirable ventral fate was established and maintained more effectively in the 3D platform. To investigate this possibility, we examined the expression of additional ventral markers, SHH and CORIN, and found they were established in both platforms by D25, had dropped significantly by D40 in 2D, but were robustly maintained in 3D ( Figure S5). In summary, the gene expression patterns obtained here – including FOXA2 and LMX1A (floorplate derived midbrain fate), (ii) TFF3 (substantia nigra specific transcription factor), (iii) PITX3, GIRK2, NURR1, and TH (mature DA markers) – indicate that the cells differentiated in 3D acquired a substantia nigra specific mDA neuronal phenotype faster and in many cases to a greater extent than on 2D, while closely resembling the anticipated trends of mDA development schematically depicted in Fig. 1e 25, 26, 27, 28. During modeling of a large number of truncations of KDM5B that comprise the PLU region, the alignment algorithm of the RaptorX server consistently identified actin molecules as templates for homology modelling. The HDX-MS data is a valuable validation source of the constructed models in this context. Remarkably, Fig. 6B with the mapping of the HDX-MS data on the model of the region show good agreement between the spectrin helical sections and slow HDX. A schematic representation of a hypothetical domain structure of KDM5B, including the FLD, is shown in Fig. 1. The FLD could not be modeled by RaptorX so interactions and the relative directionalities of the helices are undetermined from the HDX experiments only; consequently the helices are just drawn in a sequential manner.

Chem. 25, 1605–1612 (2004). High levels of MSX1, an early marker of mDA development, and PAX6, an early neuronal commitment marker, are anticipated at earlier stages of development ( Fig. 1e). Interestingly, while a 3-fold higher expression of MSX1 was seen at day 10 in 3D, by day 40 MSX1 as well as PAX6 expression levels were higher in the 2D cultures. Continued PAX6 and MSX1 expression on 2D platforms may indicate slower and/or less extensive differentiation compared to 3D 10. Furthermore, increased PAX6 expression could also be indicative of an undesirable forebrain fate in our 2D cultures 29.Chambers, S. M. et al.

Improved cell therapy protocol for Parkinson’s disease based on differentiation efficiency and safety of hESC-, hiPSC and non human primate iPSC-derived DA neurons. 31, 1548–1562 (2014). With soluble media conditions 1, 4 adapted to 3D, we engineered a thermoresponsive, synthetic hydrogel system for scalable induction and differentiation of mDA neurons for biomedical applications such as Parkinson’s disease therapy. After 25 days of differentiation, a timepoint previously found to be optimal for cell transplantation in PD models 1, we report the generation of a ~2-fold higher proportion of mDA neurons ( Fig. 2b), and ~5 fold higher numbers of cells generated per volume of medium consumed ( Fig. 2a), in the 3D platform compared to a 2D control. A crucial benchmark for clinically relevant mDA neurons is TH expression. The majority in vitro differentiation studies report 15–30% TH positive cells after 25–45 days of differentiation on 2D platforms 1, 6, 40, 41, and in 2D we similarly find 20% TH+ cells at D25. In contrast, in the 3D hydrogel we generated a higher quality, purer mDA neuronal population, with almost double the percentage of TH+ cells (37%) compared to our 2D control. A more enriched population of mDA neurons entails a more efficient use of resources, may increase the therapeutic chances of success, and reduces the risk of side effects from contaminating cell types 42. Finally, medium (including small molecules and growth factors) is one of the most resource intensive components in cell production, and notably 100,000 neurons were generated per ml of medium used in 3D, compared to 40,000/ml on 2D.
