Direct Conversion Factor Preparation Service
Introduction
Direct conversion enables somatic cell transdifferentiation without iPSCs, reducing tumorigenicity and retaining aging signatures for disease modeling. Creative Biolabs prepares high-purity transcription factors, miRNAs, and small molecules for direct cell fate conversion.
With advanced synthetic biology and engineering platforms, the service delivers stable, validated factors to generate mature functional cells, supporting reliable disease modeling and accelerated therapeutic development.

Direct Conversion Factor Preparation Service
Creative Biolabs provides customized preparation services for direct lineage conversion factors, including transcription factors, recombinant proteins, mRNA, and small‑molecule cocktails. These factors enable direct transdifferentiation from somatic cells (fibroblasts, glia, etc.) into functional neurons or specific neuronal subtypes, without going through pluripotent stem cell stages.
| Representative Factors | Main Application in Neural Reprogramming |
|---|---|
| Ascl1 (Mash1), Brn2 (Pou3f2), Myt1l, NeuroD1, Neurog2 (Ngn2) | Directly convert somatic cells into mature neurons |
| Lhx3, Hb9 (Mnx1), Isl1 | Directly induce somatic cells into motor neurons |
| Nurr1 (Nr4a2), Lmx1a, FoxA2, Pitx3 | Directly generate dopaminergic neurons for PD models |
| Dlx2, Lhx6 | Directly induce GABAergic neuronal subtype specification |

Case Study
To investigate the role of PmutNgn2 in astrocyte-to-neuron reprogramming, mouse cortical astrocytes were transduced with GFP, Ngn2, and PmutNgn2 lentiviral vectors. The expression of βIII‑tubulin, Gfap, NeuN, and Dcx was detected, along with neuronal morphology and conversion speed. Results showed that PmutNgn2 induced a higher neuron ratio, faster neurite outgrowth, and greater neuronal maturation compared with Ngn2.In conclusion, PmutNgn2 efficiently drives direct astrocyte-to-neuron reprogramming by accelerating conversion and maturation.

FAQs
Q: What is the advantage of direct conversion over iPSC-based differentiation?
A: Direct conversion is faster and preserves the biological age of the donor cells, which is vital for studying age-related pathologies like Alzheimer's.
Q: Can you prepare factors for rare or novel cell types?
A: Yes, our computational platform can identify potential reprogramming factors for almost any cell type with available transcriptomic signatures.
Q: Are the factors provided as proteins or genetic vectors?
A: We offer both. Depending on your application, we can provide recombinant proteins, mRNA, or viral vectors (AAV/Lentivirus).
Q: How do you ensure the functional quality of the converted cells?
A: We use multi-modal screening, including calcium imaging and marker expression, to verify that the cells act as intended, not just look like the target.
Q: What precautions should be taken when using these factors?
A: It is important to optimize the starting cell density and media composition, as the epigenetic state of the initial population can influence conversion kinetics.
Creative Biolabs offers a full-scale, end-to-end solution for generating the molecular triggers of cellular identity. From computational design to functional validation, we provide the tools necessary to unlock the potential of direct reprogramming for drug discovery and cell therapy.
