Abstract: The present invention provides a method of producing progenitor cells, such as cells capable of being differentiated into a plurality of different cell types, from differentiated cells. Methods of using progenitor cells in differentiation and/or tissue or organ repair and/or regeneration and/or building are also provides. Methods of using progenitor cells in treatment and prophylaxis of conditions alleviated by administering stem cells or tissue or organ derived from stem cells to a subject or by grafting stem cells or tissue or organ derived from stem cells into a subject or by transplanting stem cells or tissue or organ derived from stem cells into a subject are also provided. Also included are progenitor cells and differentiated cells and/or tissues and/or organs derived therefrom, and kits comprising same.

Abstract: A media access controller (MAC) for wireless mesh networks comprises a quality-of-service (QoS) manager to monitor consumed bandwidth of a current application flow and to compare the consumed bandwidth with a contracted bandwidth for the current application flow. The MAC also comprises a contention manager to coordinate access to a wireless communication channel for communications with other nodes of the wireless mesh network. The QoS manager instructs the contention manager to employ signaling to request additional resources for the current application flow after the consumed bandwidth is significantly less than the contracted bandwidth.
