I left an opening for light wires under the Christmas Tree, however, if you don't plan on adding lighting the opening can be filled as shown in the instructions. The Winter Village train ride looks great with lights added (see photo below) however adding lights is beyond the scope of this modification and instructions for adding lights are not included with this kit. Material properties of the PNIPAAm-PEG system may play an important role in supporting the effective generation of a mDA neuronal fate. Importantly, we show that medium conditions optimized for differentiation on 2D platforms may be effectively translated to 3D, and conceivably obstructive diffusion limitations may be overcome with an appropriately permeable biomaterial. Also, material features such as a 3D geometry, stiffness 21, topography 46, chemical functionalities 47, porosity, and degradability 15 can in general affect stem cell differentiation 19. While there have been strong advances in our understanding of mechanotransduction 48, substantial further advances are needed to elucidate the precise molecular mechanisms by which this and other material properties singly or in combination are integrated to regulate cell function, especially in 3D systems. Further experiments to systematically and combinatorially explore culture platform parameters will help elucidate how cells interpret and respond to material properties during differentiation, and thereby offer further opportunities to control cell differentiation and maturation.

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.

Biomaterials 34, 382–92 (2013). This study is the first determination of the overall 3-dimensional architecture of one of the 30 Jumonji family histone demethylases encoded in the human genome 10. Due to the high degree of similarity in primary sequence and domain organization, it is likely that the other members of the KDM5 subfamily KDM5A, KDM5C and KDM5D have a similar architecture. The structure consequently lays the foundation for new hypotheses about the function on the molecular level of this important family of enzymes. Kirkeby, A. et al.
