An intractable hematoma after cranioplasty cured by scalp cryohemostasis treatment.

We report an intractable post cranioplasty hematoma which required multiple operations. The titanium cranioplasty was for a cranial defect from surgery for an intracranial hemorrhage. Despite removal of the cranioplasty the haematoma repeatedly recurred.

Neurogenin 2 enhances the neuronal differentiation of skin-derived precursors.

Skin-derived precursors (SKPs), a novel stem cell population isolated from mammalian skin, can differentiate into neural and mesodermal lineages. Cell therapy using SKPs seems like a promising approach for the treatment of neural diseases, however, the low efficiency of neuronal differentiation limited their clinical application. In the present study, we transfected neurogenin 2 (Ngn2), a member of the bHLH transcription factor family, into SKPs by lentivirus.
