A human lamin A cDNA was subcloned into the pTracer-CMV vector (Invitrogen Corp.). The linearized vector was transfected into lamin A/C −/− mouse embryonic fibroblasts (MEFs). Stable clones were selected using Zeocin, according to the manufacturer's instructions and the clones pooled. Subsequent analysis showed that the cells in the pool were heterogeneous with regard to lamin A expression.

The direct repeat (DR)-GFP assay to measure the frequency of HR and the strand annealing EJ2-GFP assay to measure the frequency of MMEJ were performed as previously described30 (link). Briefly, U2OS DR-GFP or U2OS EJ2-GFP cells were transfected with 10 nM siRNA (Dharmacon) using Lipofectamine RNAiMAX (Invitrogen). 24 h later, the cells were transfected with the pCBASceI plasmid (Addgene #26477) and plasmids, using Lipofectamine 2000 (Invitrogen). 48 h post-plasmid transfection, the cells were trypsinized and the percentage of GFP-expressing cells was analyzed using the BD FACSCalibur flow cytometer.
The Lamin A (LMNA) assay to measure the frequency of introduction of the coding sequence for mClover at the 5’ end of LMNA using the CRISPR/Cas9 was performed as previously described12 (link). Parental or 53BP1Δ U2OS cell lines were transfected with the indicated plasmids using Lipofectamine RNAiMAX (Invitrogen). 24 h later, the cells were electroporated with 2.5 µg of sgRNA plasmids and 2.5 µg of donor template using a Nucleofector (Lonza; protocol X-001). Under those condition, omission of the sgRNA gives negligible levels of mClover-positive cells12 (link). Parental or 53BP1Δ U2OS cells stably expressing CtIP-T847E mutant were transfected with an siRNA against KEAP1 and the indicated plasmids and processed as previously described12 (link).
A FACS-based gene targeting assay was developed to monitor the targeting efficiency of a Zsgreen reporter at the 3’end of Hsp90 locus. A homology repair template plasmid was generated with the coding sequence of Zsgreen and homology arms (600 base pairs) that correspond to sequence flanking the Hsp90 STOP codon. MEFs transduced with AAV i53 and control cells expressing DM were co-transfected with a repair template plasmid and a plasmid expressing Cas9 (pX330-U6-Chimeric_BB-CBh-hSpCas9) and a gRNA (5’-CGATGAGGATGCCTCGCGCA-3’). One million cells were transfected with 200ng of Cas9/gRNA plasmid and 800ng of template plasmid using Lipofectamine 3000 (Invitrogen) according to the manufacturer’s instruction. 16 hours later, cells were selected with puromycin (2 µg/ml) for 48 hours to enrich for Cas9-expressing cells. To determine the percentage of Zsgreen positive cells, cells were by analyzed by flow cytometry using a FACS Aria III cell sorter 8 days post-transfection.
The HISTH2BK (H2B) targeting assay was adapted from ref20 for use with Cas9 RNPs. For the targeting assay, 1.25 µg of plasmid donor was used per nucleofection.

It is clear that in both human development and in vitro, LMNs and UMNs require significantly more time for neurogenesis and maturation to occur than murine counterparts. Aside from apparent challenges such as increased time in culture, study length and cost, the ability of in vitro hPSC-derived cells to exhibit mature, native functional properties are crucial for accurate in vitro modeling of adult-onset diseases. An interesting approach to artificially accelerate the aging process genetically manipulates iPSC-derived neurons to express progerin, a mutated form of lamin A, that causes the premature aging disease Progeria129 (link). Upon progerin overexpression, iPSC-derived dopaminergic neurons exhibit age-associated changes, however the non-age related effects of artificial Lamin A expression in neurons is unknown. By interfering with Notch signaling, small molecule γ-secretase inhibitors, namely DAPT and Compound E, have been shown to accelerate neuronal differentiation by delaying G1/S phase long enough to commit neurons to neurogenesis130 (link), 131 (link). These inhibitors have been shown to be effective in hPSC-LMN protocols as well25 . While these compounds have proven useful in promoting cell cycle exit, the consequences of this treatment in MN diversity is unexplored. As different MN subtype fates emerge at distinct developmental timepoints in vivo, premature cell cycle exit could obstruct later MN subtype programs.
An alternate method to generate human MNs in vitro is described as induced-MNs (iMN)28 (link). This process circumvents reprogramming to pluripotency by directly converting patient somatic cells to MNs through transgenic expression of transcription factors that drive MN differentiation. By avoiding the epigenetic “reset” that occurs during reprogramming to pluripotency132 (link), this approach has been shown to maintain age-related epigenetic signatures accrued over the lifetime of the patient133 . iMNs display unique age-related cellular defects not observed in hPSC-MN approaches. However, these approaches are challenged by genomic instability resulting from increased somatic cell expansion requirements, as well as deficient MN maturation in vitro.
It is widely accepted that the maturation status of iPSC-derived cells remains a significant hurdle to the field of regenerative medicine at large, and yet it remains largely under-explored in humans4 (link). The ability to harness cell signaling to promote maturation in vitro, rests on increased understanding of anatomical, molecular and electrophysiological data from fetal, adult and aged human spinal post mortem tissue. Projects such as the Allen Brain Atlas provide valuable templates to guide anatomical- and genomic-level evaluation of native human MN maturation and aging. However, detailed functional data on human MNs are lacking and therefore, comparative evaluation of functional maturity relies largely upon the characterization of other mammalian species, often at cost to fidelity.

Cells were fixed in 4% paraformaldehyde (Santa Cruz Biotechnology, Dallas, Texas), dissolved in PBS for 15 min, and rinsed in PBS twice. Three hundred microliters of permeabilization solution (0.1% Triton‐X‐100 in PBS) was then added to permeabilize the cells. After 15 min, the permeabilization solution was aspirated, and the cells were blocked using 10% goat serum in PBS for 30 min. Following this, the cells were incubated with either the anti‐lamin A/C primary antibody or the anti‐paxillin antibody (Abcam, Cambridge, United Kingdom) dissolved in antibody dilution buffer (0.3% Triton‐X‐100 and 1% BSA in PBS) at a ratio of either 1:200 (for lamin) or 1:500 (for paxillin) for either 2 h at 37 °C (for lamin) or 16 h at 4 °C (for paxillin). After the incubation period, the secondary antibody Alexa Fluor 647 goat anti‐mouse (Invitrogen, Carlsbad, CA) was diluted in the antibody dilution buffer at the ratio of 1:500 and added to the wells for lamin. For paxillin, the secondary antibody Alexa Fluor 488 goat anti‐rabbit (Invitrogen) was diluted in the antibody dilution buffer at a ratio of 1:350 and added to the wells. For imaging the filamentous actin for the stress fiber angle measurements, no primary antibody was added to the well. In this case, after permeabilization, rhodamine‐phalloidin (Abcam) was dissolved in the antibody dilution buffer at the ratio of 1:80 and added directly to the well. After immunochemistry, the samples were stored in a dark place for 45 min, followed by 3 PBS washes. Finally, the nuclei were counterstained with 300 nm of DAPI (Invitrogen) for 15 min. The scaffolds were kept hydrated in 2 ml of PBS and imaged using a 63× (water‐based immersion) magnification.
