Zusammenfassung
Klassischerweise unterscheidet man zwei Arten des Fettgewebes. Das weiße Fettgewebe besteht aus weißen, univakuolären Adipozyten und ist für die Speicherung und Bereitstellung von Energie verantwortlich. Im thermogenen, braunen Fettgewebe findet man hingegen multivakuoläre, mitochondrienreiche, braune Adipozyten. Erst vor kurzem wurde ein dritter Fettgewebstyp beschrieben, dem die Farbe beige zugeordnet wurde. Beige Adipozyten entstehen in weißen Fettgewebsdepots durch anhaltende Kälteexposition oder adrenerge Stimulation und zeigen eine Morphologie ähnlich den braunen Adipozyten, unterscheiden sich aber von ihnen anhand ihres Genexpressionsprofil. Dieses Kapitel behandelt die Entwicklung und das Wachstum des weißen Fettgewebes im Kindes- und Jugendalter und gibt einen Einblick in zelluläre und metabolische Prozesse, die die Fettmasse beeinflussen.
