Bone and fat: old questions, new insights

Area of Science:

• Endocrinology
• Metabolism
• Regenerative Medicine

Background:

• Adipose tissue, once viewed solely as a fat storage depot with a passive endocrine function, is now understood as a dynamic endocrine organ.
• The discovery of adipokines, such as leptin, has revealed adipose tissue's active role in systemic metabolism.
• Recent research has elucidated the intricate connections between adipose tissue and bone metabolism.

Purpose of the Study:

• To review the complex relationship between adipose tissue and bone metabolism and differentiation.
• To explore research paradigms and future directions in this field.
• To highlight the significance of multipotent adult stem cells in bone and fat for tissue engineering.

Main Methods:

• Literature review of studies published over the past decade.
• Analysis of current research paradigms.
• Exploration of future research trajectories and clinical implications.

Main Results:

• Adipose tissue plays a crucial, active role in regulating systemic metabolism and bone health.
• Multipotent adult stem cells residing in both adipose and bone tissues are key players.
• These stem cells hold significant potential for tissue engineering and regenerative medicine.

Conclusions:

• The understanding of adipose tissue has evolved from a passive reservoir to an active metabolic and endocrine participant.
• The interplay between adipose tissue and bone metabolism is complex and critical for overall health.
• Multipotent adult stem cells from bone and fat represent a promising frontier for regenerative medicine strategies.
