    TLDR Mice without the Sp6 gene have problems developing several body parts, including hair, teeth, limbs, and lungs.
    In a study from 2008, researchers investigated the role of the SP6 protein, which is produced by the Sp6 gene and is part of the SP/KLF family of transcription factors. They created Sp6 null mice by knocking out the gene responsible for coding the SP6 protein. These mice exhibited a range of developmental issues, including being hairless, having nonfunctional teeth, and presenting with limb and lung malformations. The study also found that these abnormalities were linked to misregulated apoptosis, suggesting that SP6 is crucial for the development of various organs and appendages that contain epithelium, by potentially regulating cell death processes.
