This Episode's Stem Cell Roundup:

• Tiny CRISPR System Discovered – A very compact CRISPR-Cas system has been identified in huge bacteriophages, which provides an addition to the genome editing toolbox.
• The Effects of Heart Attacks on Insulin Resistance – Scientists have found that heart attacks can affect glucose tolerance by acting on hematopoietic progenitor-derived macrophages in distal adipose tissue.
• The Hair-Raising Reason for Goosebumps – Investigators have found that certain cell types form a niche to regulate hair follicular stem cells and promote goosebumps.
• Combination Therapy to Treat Head and Neck Cancer – Combining a BMI1 inhibitor with approved PD1 blockade treatment successfully eliminated cancer stem cells in head and neck squamous cell carcinoma.
