Exosomes with Engineered Brain Derived Neurotrophic Factor on Their Surfaces Can Proliferate Menstrual Blood Derived Mesenchymal Stem Cells: Targeted Delivery for a Protein Drug.
Article in The protein journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Despite the efficacy of brain derived neurotrophic factor (BDNF) in neuro-regenerative medicine, it can't pass the blood-brain barrier. Recently, exosomes have been harnessed for targeted delivery of therapeutics into brain. Given these facts, an engineered exosome capable of BDNF expression on the surface would be an amenable tool for drug delivery. The BDNF gene was cloned into a plex-lamp lentiviral vector and virus particles were packaged using the Torano method. HEK293T cells were transduced by the purified viruses to produce and purify recombinant exosomes displaying the fusion protein on their surfaces. Western blot, Zeta sizer, TEM, and ELISA methods were used for exosome characterization. The effect of engineered exosomes on menstrual blood-derived mesenchymal stem cells (Mens-MSCs) proliferation was evaluated by cell counting assay, MTT assay, and qPCR on the bcl2 and nestin genes.
