Background: Intractable postherpetic neuralgia (PHN) can be difficult to manage even with aggressive multimodal therapies. Patients who experience uncontrolled refractory cranial PHN despite conservative treatment may benefit from an intrathecal drug delivery system (IDDS). For craniofacial neuropathic pain, the traditional approach has been to place the intrathecal catheter tip below the level of the cranial nerve root entry zones, which may lead to insufficient analgesia.

Mesenchymal stem cells (MSCs) have been successfully isolated from a broad range of adult, fetal, and other nonembryonic tissues. Fetal lung has been identified as a rich source of MSCs. However, the biological characteristics and differentiation potential of fetal lung MSCs remain to be explored.

Objective: To evaluate the hematopoietic reconstitution of implanted NOD/SCID mice, after intra-bone marrow cavity injection (iBM) of human umbilical cord blood (CB) mononuclear cells (MNCs).
Methods: 24 female NOD/SCID mice were divided into different MNCs dosage iBM groups (3 x 10(6), 1 x 10(7), 3 x 10(7) cells), tail vein intravenous injection (iTV) group (3 x 10(7) cells) and control group (iBM of medium only). CB MNCs sorted by Ficoll-Hypaque were transplanted into left tibia bone marrow cavity of 6- to 8-week-old NOD/SCID mice, which were anesthetized and sublethally irradiated (270 cGy (137)Cs-gamma irradiation).

Objective: To explore an optional condition to induce mouse embryonic stem (ES) cells to differentiate into endothelial cells and to establish in vitro models of vasculogenesis and angiogenesis.
Methods: Mouse ES cells were cultured in differentiation medium containing a cocktail of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), interleukin-6 (IL-6) and erythropoietin (EPO) in 1% methylcellulose to induce formation of embryoid bodies (EBs). At day 11, EBs were harvested and suspended in rat-tail collagen type I with the same cocktail of cytokines cultured for three additional days.
