Low-Dose Tamoxifen Induces Significant Bone Formation in Mice.

Use of the selective estrogen receptor modulator Tamoxifen (TAM) is a mainstay to induce conditional expression of Cre recombinase in transgenic laboratory mice. To excise β-catenin in 28-day-old male and female Prrx1-CreER/β-catenin mice (C57BL/6), we utilized TAM at 150 mg/kg; despite β-catenin knockout in MSC, we found a significant increase in trabecular and cortical bone volume in all genders. Because TAM was similarly anabolic in KO and control mice, we investigated a dose effect on bone formation by treating wild-type mice (WT C57BL/6, 4 weeks) with TAM (total dose 0, 20, 40, 200 mg/kg via four injections).

Immunophenotyping is critical to the diagnosis of MS, as it can be difficult to differentiate from other diagnoses including lymphoma using conventional light microscopy.

This 9th Symposium on Hemostasis is an international scientific meeting held biannually in Chapel Hill, North Carolina. The meeting is in large measure the result of the close friendship between the late Dr. Harold R.
